This is a bit of a strange one, but what I think is happening is this:

• I have a dual monitor setup.
• I have DF set up to hide items on the main taskbar and show them on the 2nd screen that they are active on.

Depending on the type of monitor connection (DP/HDMI), when you lock windows and turn off the monitor, windows actually deletes the monitor from it's setup while it's off, causing the system to become temporarily a single monitor system.

What happens when you turn things back on is:

• All apps open on second monitor get moved to the first.
• Because they are showing on the first the second DF taskbar doesn't have any taskbar items on it.

However:

• The main windows taskbar isn't refreshed and the taskbar items are hidden from that taskbar as well.
• That means that any apps that were on the second monitor are missing from both taskbars.

To get them back I need to alt-tab to each app and the taskbar items re-appear as I switch to each app individually.

Possible solution:

• Check windows event either for unlocking or adding/initialising second monitor.
• Refresh all tasks bars when this happens.

Hi,

Being a work PC, I sent through the log to your support email rather than attaching.

I was able to reproduce the issue instantly in about 20 seconds - so you shouldn't need a timestamp.

My process:

* Open outlook, notepad, notepad++ and firefox on screen 2.
* Start logging
* lock pc
* turn off both monitors
* turn on both monitors
* unlock pc

And the items were missing.

I alt-tabbed and clicked on one of them and the items returned.

Let me know if you need any further.

I believe this only occurs with certain types of monitor connections. In the past when I've used DVI/VGA I've never had this issue or had applications be moved to the first monitor when turning off - as I believe Windows keeps the monitor 2 connection alive while it's off - continuously sends signals down.

When using hdmi, turning off the monitor kills the data connection, so all apps are moved to monitor 1.

Hopefully it's simply an event to detect that the new monitor has been re-established and refreshing the DF taskbar to get them back.

Fantastic. Thanks for the quick response.

Did it end up being a windows thing or a df thing?

Hi,

Installed beta 4.

It doesn't reappear on the taskbar instantly, but seems to eventually appear after about 10 seconds.

So based on your response I guess there is nothing that can be done to make them appear quicker than that?

As in add them back on a timer while checking for existence, then retry on a exponential back-off of some sort - ie 1, 2, 5, 10, 20 seconds?
