After installing ACAD LT 2012 and activation seemed to work a while. I migrated printer and pens from 2009 and adapted the menu. I can work with it.
After restart next day, Acad 2012 LT freezes while pressing "open" or "save as".
Opening files via Windows Explorer works, the program does 10 minutes auto save, so the file is not lost completely.
The previous 2009 does the same afterwards.
Opening 2012 and resetting migration and menu makes it work again.
It might have something to do with Plotters and pens, which sounds weird - could that be?
Anyone a longer lasting solution?
Yours, J.W.
