Do you have any plug-ins installed?
Do you tried reinstall the FM?
I've got Developer Assistant by 2empower. I'll disable it and see if that helps.
Thank you for your post.
This is a known issue. I will add this thread to the original report. When more information is available, I will post back here.

I am not familiar with that plugin, but I would certainly try removing it entirely and see if that solves the issue. It may not be compatible with 14.
I've had many similar cases with clients.
Thanks, TSPigeon. I'm glad it's not just me.
I disabled the plugin and the crash still happened, if that helps anyone.
