For flash in X64 Win7. Windows 7, with IE8 has both 32bit and 64bit versions. I thought it was a little weird, but i wont complain. If your hardware supports x64, then use the 64bit version of windows 7. If something isn't working, it's probably either your fault, or your computer parts are old. Creative for example, are serious rectal sphincters, they refuse to release new drivers for older hardware to force people to upgrade. Now, i just don't use creative products anymore. Any problems with firefox, is firefoxes problem, i dont have any issues with opera 10 beta3. Only problem with windows 7 i've experience.. Bluetooth. Doesn't support audio devices like headsets. Also, it took me 3 hours to get my robot to connect to my bluetooth adapter AND work in a terminal program. (but that's probably the UART bluetooth adapter on my robot, cheap piece of junk. Had same problem with XP) Edit: My bluetooth adapter i use on my desktop, is a $2.50 one i got from dealextreme. works fine with other devices besides audio. But i read theres a fix, possibly 3rd party, in the works.
