Ok, uninstalled, removed DF directory, cleaned out registry refs and reinstalled from your link.

No freeze ups yet.

So far, so good. (at home) I having seen any freezine all weekend (yet, crosses fingers). Monday I should know how beta 15 acts at work. Hopefully, this is it...

Either way, it looks like I was the only one seeing this kind of thing, so I wouldn't let that hold you up...

Ok, just got a button freeze again. No screensaver involved. Had windows Picture/Fax viewer up. closed but button remained.

Now here's the wierd part: If I RE-open Picture/Fax, it takes the place of the frozen button and reflects the picture names as I scroll through a directory. Close Picture/Fax and the button remains frozen.

(I also have FireFox open and when I move it to the primary monitor, it's button also Freezes. Return it to 2nd monitor and it picks back up where it's frozen buttons was. Minimizes and all. Close it, and the button freezes.

At this point, everything I have on the 2nd monitor acts the same way, until the bar is loaded with frozen buttons.

If I scoot a NEW application to the 2nd monitor, it takes the place of a frozen button. It now reflects the new window and minimizing/unminimizing works. Move the window off 2nd monitor and the button remains... frozen.

Log file shows no errors.

I've switched back to XP's standard theme, so that's not the problem. The only other things I have (and also have at home where the same problem happens) are Kana Launcher and Firefox run from my USB.

Next up I'll not run Kana Launcher for a few days and rule that one out...

I'll leave it running in this frozen state if you want me to try anything...

The task bar is still functional when you move apps to it's window, it just doesn't "clean up" when you close or move them off...

After a weekend of running without Kana Launcher and no freeze ups (I thought I had it this time, dang!) I finally got a freeze late last night. So Kana Launcher is ok... The only culprit left to nix is Portable Firefox (for USB). I'll install beta 17 and continue testing...

Yep, that's the one...

Well, don't know if this helps or not. Stopped running Portable Firefox AND Kana Launcher AND WinAmp AND Zune theme and ran Google Chrome instead. Just got a button freeze up... No screensaver...

Still had NotePad++ running. I'll nix that and try again tomorrow...

Hmm, just right-clicked on DF taskbar to check release number (beta 17) and the dialog popped up, and the screen flashed like crazy several times (icons and such refreshing) before it settled down (kind of freaked me out). Then, the DF taskbar buttons froze. (see attached). Subsequent launches of settings window behaved as expected (no flashing)

Programs running on second monitor: Google Chrome, NotePad and NoteTab Light.
Programs running on primary monitor: Word and Excel.

Nope, nothing running from USB drive. Earlier (lunchtime here) I was running a Windowed game from the USB, but this occurred about an hour after I shut the game down. I'm using NoteTab Light instead of Notepad++ (to rule that out) and Google Chrome instead of FireFox. Last two freezes have been while Google Chrome was running (which may or may not be related)

Also, I've had the random wallpaper function stopped all day, so there would be no wallpaper swapping.

I do have McAfee's running here and at home. I can't shut it down here at the office (though I can disable it), but I can at home. I'll do that tonight.

Yeah, I've been racking my brain trying to pin-point apps that may be causing this and shutting them down (apps that I'm running on both my machines that are seeing the freezing buttons). The last thing that is running on both machines is McAfee. (though at home I always have "On Access Scan" disabled). I'll un-install it for a few days and see what happens.

Cool. Thanks!

Interesting: Installed DF beta on my son's computer. Totally different box with different software than the others.. Button freeze happens on his too! What similarities? McAfee. I'll uninstall McAfee on mine and see if the problem goes away...

Got it. I'll be on Windows 7 this weekend, but I'll get it installed on my son's computer that was seeing the same problems.

OK, got beta 18.

The only similarity I can see between the three machines I'm running DF on (and where all have seen the freezing buttons) is McAfee Enterprise addition (and perhaps Firefox). You think this might have something to do with the thread locking issues?

I've been crossing my fingers and hoping not to jinx things by saying that everything has been working perfect as far a buttons freezing. There, I've said it.
