Basically I downloaded and Installed the Alt-Tab Task Switcher Powertoy for Windows XP locatable <a href="http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx">here</a> It worked when I installed it. But when ever I restart my computer it stops working and I have the default basic Alt Tab screen. It works again if I re install it over the existing instillation but then stops when ever I turn off my computer. I also have the Tweak UI power toy from MS. Maybe something in there conflicts with the Alt-Tab thing is all that I can think of. But I have had a look and cant fix it. Anyone that could help me, it would be greatly appreciated.
