When there are 2 or more Skype windows on screen, windows explorer will instantly crash and it will keep crashing after restart as long as there is more than one skype window on the screen. When I leave just one, it works normaly.
One window: (it doesn't need to be the main window) Opening another window: (in this case it's the settings but it can be anything, a chat, a call, even a confirmation dialog)
With media player it is different. It crashes only upon switching from Now playing to Library or vice versa: . . It is especially annoying when I plug in a flash drive during music playback and it switches to library automatically.
These 2 programs are the only thing that cause explorer to crash. It works normally with all other programs and never crashes by itself. I've had this problem for years, ever since I installed windows 7, but it was only media player and wasn't such a big deal. I used a very old version of skype which worked, but now I was forced to update and this new version is practically unusable due to this problem.
I use Windows 7 Home 64bit with Classic shell and classic theme. Uninstalling Classic shell and restoring the default theme does not solve the problem. sfc /scannow does not solve the problem either.
