Feb 02 patch bug. Cannot Alt-tab to Windows.
I've had that issue for a few patches now. If I repeatedly alternate between pressing the Windows key and clicking on CoH's screen, I can eventually get the taskbar to take focus and then do whatever I want. The only way I found to negate the problem was to play in windowed mode instead, which I don't really want to have to do.
running in windowed mode is an easy workaround, so far havent had any issues with windowed mode
i like windowed mode more because it makes switching to different window a lot easier, especially since i usually run with 2 monitors

i have that issue too Snowy. I noticed it probably around i19 release actually. Just figured it was another windows feature.
Yesterday I was able to alt-tab out of City of Heroes. Today, the CoH display overrides everything but the task bar when I try to alt-tab. The ONLY difference in my machine from last night to today is the patch that was applied today.
