I have already seen this problem, with Alt-Tab Replacement (TaskSwitch) of [url="http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx"]Microsoft PowerToys[/url] but I think that the real problem is in the task switch program and not in the 8start.
I do not understand because this softwares see 8start like a normal application,
normally with alt-tab, Windows Xp not see 8start. !?!?!?
My suggestion: use [url="http://www.ntwind.com/software/taskswitchxp.html"]TaskSwitchXP[/url] is a very nice freeware program with the same function!!!
