I've had that problem, I've even tried reinstalling it when it happened (which didnt work). I finally figured out what was wrong -- the classview information and it listed the same classes thousands of times. Everytime it loaded the file and created the classview it would keep looping and then crash. I ended up just opening my files in notepad and looked around in my code for something that might be wrong. I was missing a brace! Silly, eh?
So try opening your files in another editor and compile them and see if it says you have any sytax errors. Fix them and then reload your project in msvc++
Or, you can just ditch msvc++ 6.0 completely because it's a piece of crap
