Is there a program/hack that will enable window snapping in Win XP? (Like in Ubuntu)

allsnap (easy to google for). it has some shortcomings in 64 bit versions of windows, though - namely you can only run the 64 bit or 32 bit version at a time, not both at once, and each will only snap 32 bit or 64 bit native windows. For example, firefox is 32 bit native, so if you run allsnap 32 bit, it will snap that... but 64 bit native programs like windows explorer, or 7-zip 64 bit, or a myriad others, will not snap. It's aggrivating, but it's all I can find.
