Its probably improved since then, but was never unstable on my PC.
Its more likely due to the fact that most school/college computers are never set up right, and because they simply mirror the image onto all of them, they all have the same issues.
I doubt it was the programs fault
Heck, our University computers are meant to be faster than mine, haha, as if they are. Crash here, slow down there, blue screen everywhere else.
