I'll just illustrate this one with an example... Let's say I'm having a chat with "Rob" and "Jane". Rob says he's going out for lunch and will be back in an hour; my conversation with Jane is inactive, so I decide to minimize the window, leaving it from Rob's tab. Then suddenly Jane responds, and the minimized tab on the taskbar starts to flash, but in
Rob's name. However I don't notice that it wasn't Rob - but Jane - before I restore the window and see
her tabbed conversation flashing in the window. It's misleading and annoys the hell out of me
