I have a small issue that seems to occur occaisionally when I'm navigating around on my pc, sometimes I can be on the internet and open a page and I get an error mentioning just-in-time debugging then my window will just close sometimes it happens when I open a program too.

What is this? I don't think I have the software installed to even turn this off. How do I get rid of it?

as far as I can tell this is an automatic debugger in dot.net framework-- so if you have any software that runs on that (it's a programming framework/language by Microsoft-- you may)
there are many things that might utilize this-- yours might need un/reinstall-- or update.
Add/Remove programs -- look for .NET framework--you could just run Windows update-- see if it lists any upgrades for it.

Ahhh I see thanks for the advice I'll have a look on Windows Update first if there's no updates I'll uninstall it and reinstall.
