I know there is that "technical discussion" forum, but I want to get to the Topaz crowd. I just downgraded to Win7 64-bit from WinXP 32bit. In the old machine I had Topaz and Nik plugins working. Slow, but working. In the new machine it is really, really FAST! WOW! It takes it only about 1 second to shut down PS and also give the Einsteinian message "a problem" made it shut down Photoshop. Do others get Topaz products to run on 64-bit Win7? I really miss it.
