Goto
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced]
create a dword value named "TaskbarGroupSize"
double click the new value and enter the number of open windows before XP groups them together.
I prefer 2, but you can go higher.
Log off and log back in. You should be good to go. Happy tweaking. (The latter was added after first submission)
