Fusion 8 and 9 glitch with tab key

Hey Guys !!

I am new to this forum. I really appreciate the work you guys have done in this forum so far.

I have been having issues with the 'tab' key in both fusion 8 and 9 (free versions). Every time I use the tab key it freezes Fusion and I have kill fusion from task manager.
Has anyone here experienced this on their machine?

Would appreciate any help from you guys.

linux, mac os or windows?

but so far no one posted something similar.

did you bind the tab key to a special script or where do you use it?
