XnView Software

In XnViewMP 0.68 on Win7x64 there is
no reaction at all when clicking
File > Select TWAIN source or
File > TWAIN scan.

The menu just closes.

I am using three displays.
but the Epson Scanner V300 is working very
well with very old versions of ThumbsPlus and Photoshop
in this environment.

IF you have twain driver x32, you need the x32 version of XnViewMP

If you are using XnViewMP x64 you might try installing XnViewMP x32 as well and test that -- the very old versions of ThumbsPlus and Photoshop you are using are no doubt x32.

TWAIN is confusing on x64 systems and I can't immediately offer an explanation, but both versions of XnViewMP can be installed at the same time and it would be a simple test to perform...

Thank you very much for your help.
Your answers does explain the problem very well.
AND: The problem is solved!
Did install 32bit XnViewMP too and TWAIN32 now works with it.
