Hi All,

after switching from 10.0 to 10.1 editing one of my favourite feature classes causes ArcMap to crash!!!

The FC (point) is member of a network datset. If deleted from network datset, editing is fine!
Putting it back into the network dataset causes crashing again. FC has very few attributes (text, double, short integer).
Crash occurs everytime I change a cell in the attribute table and move to the next cell.
Tried update on network dataset to 10.1 - doesn't help.

Any Ideas?

Thanks in advance
