The problem lies in tabbed conversations. When I am using them the window does not flash at all, even if there is only one conversation window present.
I turned the Tabbed Chat off, and the windows began flashing again on the taskbar.
VProg, try taking tabbed chats off and see if the flashing returns.
At last I have my flashing back! (that sounds wrong ) Though at the expense of tabbed chats. Well i can't have everything.
