Missing Face Crash

[StormEagle]

When I try to fill in a missing face the program keeps crashing. This is really annoying and it's getting in the way. Is there already a solution for this or is it only my client that's causing this to happen?

I took screenshots of it happening.




When there's a hole it saves


But when I fill it in this happens


This happens for every mesh I make and it sometimes comes up with another message:
