Virtools and buggy programs

Has anyone used this program?
It is one of the most annoying and buggy programs I have ever used.

I have to create a game working game level within Virtools for my project at University.
I have never shouted at a computer so much! XDDDDD

It works one minute, then dies the next.

Have you even come across this program or what other buggy programs have you used?

As far as I know, GVSU's CS department actually uses good software: GCC, KDevelop, Putty; stuff that's widely used and supported; plus, many of their computers run on Fedora, my favorite distro of Linux. On the other hand, the rest of the University uses stuff I find ridiculously annoying (IE7, FF2, Office 2007). I do my part as a good citizen and install Adblock Plus with EasyList on every one of their crappy outdated Windows computers that I use, though.
