Hi, (sorry if I don't explain this correctly, I'm not English speaker)

This is just to report a possible bug.

I think there is a bug in the latest version.
I see that this version has a new feature to simulate the request for attention of Windows normal taskbar behavior.
I have Windows XP Sp3 with the latest updates, and no viurs or something like this.

I saw a strange behavior having, for example, 3 o 4 Messenger Windows requesting for attention at the same time.
I couldn't reproduce that, but in that situation, the DisplayFusion taskbar lost the 3d button effect for all windows, and you can only see the window icons, the text of the buttons appear black and with bold font, and the thumbnail window image didn't work.
I had to close DisplayFusion and open it again to restore to the normal state.

I just notify this.
I think you have to check that, it may be a reentrant function problem.

Regards
