I'm having trouble with my new Fujitsu fi-4120C2 scanner with WIA and
Leadtools Raster Imaging Pro.  Everytime I try to scan using WIA,
twnSession.Acquire(flags) returns DialogResult.Cancel.  Everything
loads properly and the paper actually goes through the machine, with a
dialog box on the screen.  Then, once it's finished scanning, the
results are equivalent to pressing cancel - it just quits. 
However, using Windows Scanner and Camera Wizard and WIA to acquire, I have no problems.

Using standard TWAIN and Leadtools, there is no problem.  This
error has occured on multiple systems with the exact same result. 
It doesn't make sense because I also tried an HP scanner, and WIA/TWAIN
both work fine under all conditions.  Is there an issue with WIA and this Fujitsu scanner?  Thanks in advance.

The program you used to scan from the Fujitsu WIA driver maybe using WIA specific code to perform the acquisition.  I would suggest downloading Twacker.exe from www.twain.org | Downloads (very last link) and try scanning with this application.  If the same issue occurs using this program you know the issue lies with the WIA Driver and Fujitsu.  If the scan is successful then the issue lies with LEADTOOLS.
