I'm not sure what you're talking about.....
Do you mean that you go to your shared folder using Windows Explorer and when trying to open it, your computer crashes?
Or do you mean that you try to go via the LW Library to the shared folder?
If it is the first one, and it would be my computer, I would check first whether I caught a virus with the last file(s) downloaded; though I don't want to scare you........just a thought of mine.....
