Ubuntu 7.1 + Qcad Professional 184.108.40.206.
System has worked OK as I became familiar with it. However today I get these symptoms:
1. Qcad window is larger than the computer screen. In particular, the command line disappears below the bottom edge of screen.
2. The Qcad window greys out and buttons at top of the screen are inoperative. When I try pressing one with the mouse, the screen jumps up and reveals the command line. When I try clicking in the command line, the Qcad window jumps down revealing the menu bar at the top and obscuring the command line.
3. To get out of Qcad I have to force quit.
I have send the whole installation to the trash bin, emptied the trash bin and re-installed from the tar-ball.
System still gives the symptoms detailed above.
Thanks in advance for your help
