Sorry that I didn't reply earlier to your June 30 post, but the problem is that when I try to close the application, I get a message that a backup hasn't been done. When I try to back it up, it acts like it has backed up but then I get the same error when I try to close it again. I always have to resort to the Task Manager and abort LBC manually. That's the only way I can get out of it. I also cannot add links to it. I finally had to uninstall it from that computer. I tried reinstalling and the problem reappeared. I run it on another PC and it works OK there except that if I create a link to a file, it will start the application, but (let's say Excel) but won't actually open the file.
