QCAD Professional 2.1 (I think but can't open anymore to get version)
I enabled rulers and grid lines and QCad froze. When I restart Qcad opens up as usual but the FILE and EDIT menu option are on the right side of the menu bar and nothing works. Ubuntu says "QCad - [unnamed document 1]" is not responding.
Is there a file that holds preferences that I could remove to get QCad working again or do I need to re-install?
