Bug? Problem Exporting Project

I get error when exporting Project, Any ideas ?

Arthur

Seems like one of the project files is corrupted or locked.

OK, luckily I have had a backup, and restored it. Now It all woks fine.
I hope this will not happen to often,...

I really insist again on adding SAVE AS feature to the IDE
For the Software Guru - like YOU, it should take only few seconds ;-)

Thanks for quick response - Arthur
