The next time it crashes with the "Object reference..." error, could you please note the time that it happened, and send the debug log located in %APPDATA%\DisplayFusion\DisplayFusion.log? You can located it easily using the "Open Log" button on the Troubleshooting tab.

Thanks!

Nope, same steps apply for any crash, just let me know how it crashed when you send the log. You can attach it in this Discussions topic, just leave the "Protect these attachments" option enabled.

Thanks! To clarify the circumstances of the crash: Did DisplayFusion completely crash, requiring you to re-launch it? Or did it just throw the "Object Reference..." error?

Ok, thanks for the logs and the extra details. We've found something interesting in the log. It seems that DisplayFusion is shutting down, and then crashing during the shutdown.

The interesting part is that it doesn't appear to be DisplayFusion that's shutting itself down, as we're not seeing the line in the log that would indicate that DisplayFusion told itself to shutdown. So, it looks like some other program on your system could possibly be sending the WM_CLOSE message to DisplayFusion, and then when DisplayFusion is shutting down, for some reason it's crashing.

The next time it crashes, would you be able to start it backup, and send me a copy of the info from the DisplayFusion Settings > Troubleshooting tab, before opening or closing any other programs? This way we'll be able to see a list of the processes running on your system at the time of the crash, and maybe we'll be able to see something interesting.

If we can find the program that's telling DisplayFusion to shutdown, hopefully we can install it and reproduce it here for further debugging.

Thanks!

Ok, thanks! I didn't see anything in the process list that I would suspect is causing this issue.

We're going to add a bit of extra logging to Beta 6 to try and confirm that DisplayFusion is actually receiving a WM_CLOSE message before it starts shutting down. I'll let you know as soon as it's available.

Thanks!

No worries, hopefully we'll be able to get this sorted out!

Ok, Beta 6 is now available. Could you update to it, enable Logging: All Lines on the Troubleshooting tab, and send a new copy of the debug log, along with the time of the crash the next time it happens?

Thanks!

Just wanted to follow-up to see how it's going with 5.0 Beta 6. Any crashes since updating?

Ok, we think we've actually gotten this fixed up in 5.0 Beta 7. I'll let you know as soon as it's ready to try out.

Thanks!

Excellent, was just about to post a follow-up

Please let me know how it works out!

Ok, we're making a few more changes for Beta 8, so I'll let you know as soon as it's ready to test.

Thanks!

We've just released DisplayFusion 5.0 Beta 8 (http://www.displayfusion.com/Download/Beta/), could you give it a try and post another log if it crashes? Please note that I'm looking for the debug log (C:\Users\username\AppData\Roaming\DisplayFusion\DisplayFusion.log), not the Troubleshooting info

Thanks!

Ok thanks! We'll check this out.

In the meantime, do you remember if you were having this issue in 4.3? Or did it only start in 5.0 Beta 1? If you could try 4.3 again to confirm, that would be great!

Ok, would you be able to try 4.3 anyhow? If it's something that broke between 4.3 and 5.0 Beta 1, we should hopefully be able to narrow down what change made it occur.

The only settings that might be affected by switching back to 4.3 would be the wallpaper settings. Everything else should be ok. DisplayFusion makes a backup of the settings any time the installer runs, so even if something gets messed up, you should be able to restore the backup after updating to 5.0 again

Yep!

Interesting! Does this happen every time you try to click a Dropbox tray notification?

Ok, interesting! Too bad it's so intermittent, makes it hard to track down

At any rate, we've made some changes for 5.1 Beta 1 that should hopefully help, so I'll be sure to let you know as soon as it's available to try out.

Thanks!

DisplayFusion 5.1 Beta 2 is now available, could you give it a try when you have a chance and let me know if you still experience any crashes?

Thanks!

Ok, thanks! These logs so far haven't shown anything helpful unfortunately

Can you enable the "Logging Trace Mode" in the DisplayFusion Advanced Settings, and then send another copy of the log when it crashes again?

Thanks!

Nope, just the Trace Logging please

Ok, thanks, unfortunately that log doesn't show anything helpful either

I think we'll need to try disabling DisplayFusion features one at a time to see if the crashing goes away. It's a bit of a pain, but hopefully we can narrow it down to a specific feature and go from there.

Could you start by disabling the TitleBar Buttons? How long is it between crashes usually?

Sounds good, thanks!

Just wanted to follow-up and see if you were still having this issue? If you are, could you try updating to 5.1 Beta 13? We fixed a lot of the hook code, so hopefully your crashing will be all fixed up too

Excellent, glad to hear it!
