you will need to give more information.
In the heading you say that "viewing" files locks up windows, but in your post you say when doing anything "other" than viewing a file your system locks up.
Which is it?
What types of files are you attempting to use? (Do anything other than view). What is the file extension, (ie filename.abc where .abc is the file extension).
What are you trying to do with the files, eg open them? double click them?
Can you open (start up) any other programs, eg from the Start menu > All programs? Do they work ok?
Does this problem occur only in Windows Explorer? Or does it happen on desktop shortcuts as well?
You mention right click. Are you saying right click doesn't work? What happens when you right click a file, do you get a menu? What happens when you try to select one of the menu options?
Have you tried to Restore to a point before you installed the scanner?
When I do anything other than view a file I've stored on drive C:, CF card etc. my system locks and I have to "end program". I recently installed a new scanner and didn't have this problem before installation. I don't know where to start but it may be related to right clicking my mouse to get the properties or delete commands to prompt. Please give me some direction.
