Are you getting that stupid "This software might not be compatible with Windows XP" garbage? My Intellipoint 3.2 software came up with that and it worked fine (Thank you NTCompatible for that one). Netscape 6 (or 6.2 I can't remember) is rumoured to display that too. The point? 9 times out of 10 that advice can be safely ignored. The exception being stuff like the Creative Win2k Live!Ware 3.0 package (although admittedly that didn't bring up the warning box). Something it installs (The Windows drivers I think but I'm not sure) screws up pretty badly under XP which led to much frustration and a reinstall (although I could of possibly booted into Safe Mode and rolled back the driver I wasn't aware of the possibility at the time).
