Problem creating views - they work fine for me but not for other users

Has anyone else ever experienced such a problem? This is an application that we've been using for more than a year, it's been working fine. I'm adding some forms to it, that was working OK ... however, now when I try to add new views, they work fine for me but not for any other users, although they're shared. The other users either get a blank page, or the page hangs, or they see two sets of navigation tabs and nothing else. This happens when I log in as another user also. There's nothing wrong with my new views, even if I just duplicate an existing view that works correctly, it doesn't work for other users.

Occasionally if I try and try, a new view will work, but most of the time it doesn't, and I'm wasting a ton of time trying to create a couple of new views. If anyone else ever experienced this and has a suggested solution, I'd appreciate it.
