Scanning problems

XnView 1.80.3/Win (Datetime: 06.09.2005 16:24:00; filesize: 1037312 bytes).
Mustek BearPaw 2400CU Plus USB Scanner via TWAIN
Windows 2000 SP4/rollup1 RUS
After clicking 'Scan...' button/menu item TWAIN driver window opens; then, after clicking 'scan' scanner starts; then, after scanning finished, XnView main windows closes, leaving TWAIN driver window open. Rebooting/repeating again gives the same result.
Photoshop and other TWAIN-supporting programs as well as XnView 1.60 (Datetime: 13.05.2003 08:43:52; filesize: 714240 bytes) work well.
What's the problem?

I tried to remove the option "Add XnView as applications for USB
events (camera, scan, ...)". After reboot, I could scan images using 1.60 and 1.80.3! But, if I tried to scan too large images using TWAIN driver's built-in image preprocessing (an option called 'White background'), the scanning failed after scanning document. I think that this last failure was caused exclusively by TWAIN driver, because I have too little free space on a drive where TWAIN driver can create temporaries (less than 32M). But when I've unchecked that option, the scanning in 1.60 an 1.80.3 had no problems.
But there's one "but": neither RC1 nor any version of RC2 doesn't work; they fail immediately after starting acquire, even before TWAIN driver window appear.
So, one of the problems is resolved. Waiting for you to resolve others ;)

I have a similar problem. I'm always getting "Acquire returned false" when trying to scan something in XnView, but Photoshop CS2 and other software works fine.

Strange, other software use TWAIN driver?

Yes. Photoshop uses TWAIN interface.
