I appreciate your work but I hate this. The first thing I do on an XP or Vista install is turn off the task grouping.
With no text on the items in the taskbar this doesnt seem like a possibility.
My issue, and this comes up in software design often, is by making everything visual and grouped... the problem of finding 2 similar apps with similar names is solved, however... if i know what i am doing already, now there is an extra step of mouse over and
then click on the thumbnail to get back to my app. Further, if I have 5 or so IE tabs, that could mean moving my mouse back and forth across the screen. With monitors at 22 and 24 inches, this becomes a hassle.
