    I have almost the same problem. The first scan works well in Photoshop but after that the scanner doesn't respond and PS freezes. I think that's a bug in the driver. Unfortunatly the support for Mustak scanners are the worst that I've ever seen :-(

I'm having the same problem with my Mustek A3 and I didn't have this problem at all until I installed the newest version of McAfee virus protection...ever since I installed that stupid program, every time I go to scan something with the Mustek scanner through Photoshop, now it freezes on me at the initializing scanner screen. I even tried the system restore to reset everything before the McAfee was installed and miraculously the scanner works perfectly again. So whatever McAfee has on that disk is screwing up my scanner which is really irritating. And yeah, I tried downloading the new drivers from the Mustek site before I did the system restore and that didn't help at all either.

I have a Mustek Scanexpress A3 USB scanner. I''ve installed all software and hook up the machine. When I try to scan using Photoshop of the bundled "Panel" software, the program locks. I'm using XP...

It could be something to do with the bundled software having a missing or corrupt TWAIN32 file.. But you can Scan using Windows XP itself.

Scroll down to the Scanning part, and see if that is of any use to you..

Hope this helps
