Has anyone has problems with simple design tables? I made up a small block with a few changes to width, length, height. Added a shell. When it came to adding a variable to the design table such as the height by double clicking the model SW freezes. I can unlock it by going into standby mode and turning back on. As soon as i try the actions again the same problem comes up? The lock up has detrimental effects on the mouse when you switch the desktop, so i have to shut the computer down.
