Set an exception in taskbar behaviour?

I like the way the taskbar works in windows 7, but for one program (my messenger, icq) the new behaviour is quite annoying. When someone writes to me, i only see who it is after i hover over the icq-icon in the taskbar and only then i can see where to click to open the message-window in question. Much more "work" than with the old taskbar, where the blinking area of the message-window tells you instantly where to click and who it is that has texted you.

I'd like the icq-icon only to affect the icq-contact-list, while the message-windows open on the empty right side of the taskbar. The behaviour of everything else shouldn't be changed (i don't want the taskbar to be completely vista-style).

Old taskbar behaviour for icq, new taskbar behaviour for everything else would be ok too.

Is this possible?

Thank you!

/edit: even if i only chat with only one person, i still cant reach the conversation in one click. I still have to hover over the icq-icon and decide between opening the contact-list od the message-window. Annoying.

That would (technically) have to be done at the program level. It is possible though. You'd have to wait for a later release to include seven support and hope the icq devs add that function to it (hint: bug the hell outta them =P )

I found this a little annoying as well, but it was mostly due to the time you have to hover for it to show up. I changed the settings through the reg to 40 and it's alot more bearable if you're a quick mouser.

Mouse Hover Time - Change

Thanks! Changed it to 40ms and the whole taskbar feels much better now.
