Hi Guys,

I have a very weired problem here. When I click the "file property" button on the menu bar, it turns grey and the property dialoge box doesn't come out. Afterwards, if I right click the drawing area and choose "property", then the program crash. I have tested some other different drawing files, but same thing happens all the time. I have also tested a single file on mine and my colleges' computers, obviously my one is the one plays up. I have repeated a few times, but it just does the same thing. I have also tried restart the computer or a clean reinstall (C drive setting file cleanup and windows registry cleanup), but none of them make the program work. It never happens before but since today.

Does anyone have a clue?

Thanks in advance.
