Twain import having to hit ctrl,alt,del going to task manag

Hello, I have had a problem with the 1.01 version of k-pacs. I am importing from a twain source film digitizer. When I scan the film in the image does not appear on the import image bar. I hit the file icon then the image appears. When I try to import another image, to the same file , the program locks up. The only way I can import more than one image is to scan with the twain, close the scanner, hit the ctrl,alt , del keys. This brings up task manager. Instead of closing the task I just close the task manager. This will bring an image on to the import bar. I then need to open the twain again, scan another film then do the ctrl, alt, del then open the task manager, again , then close the task manager. I have to do this for every image to be scanned. Once the images are on the bar I can create dicoms sucessfully.
I am using win xp with sp2.
