Windowed Fullscreen Alt-tab inconsistent.

Sometimes when playing in WF mode it will alt tab normally. At some point, something happens with the game and then when alt-tabbing, the windows taskbar just appears over the bottom of the window and it doesn't tab properly, no other windows overlay the game. This has been happening for a while, not with the latest patches. The only way to fix it permanently is to restart the game client. However, going to fullscreen mode lets it work properly while you stay in that mode.

This is Windows 7 64Bit, in case it matters (it probably does).

I am have this exact same issue. It had previously worked fine for a very long time and now suddenly does what DemonicGoblin has described.

Also Windows 7 64-bit.

Having the same problem, hope we get some word from GGG or some way to fix it

+1 Same problem.

Pressing just Windows-Key and with mouse picking something else on the toolbar will switch though. Picking any window with mouse during Alt-Tab or Windows-Tab does not work either. While holding Alt-Tab then mouse over to other screen to interact with something does work and switch focus.

Was there ever a solution or explanation for this behavior?
