Irricad

Yesterday I got a message window that said: "Encountered an improper argument" and there was no means of acknowledging or escaping. I managed to clear the window by moving the cursor to the task bar, and by means of a separate monitor get the cursor to the upper right corner of the screen ...

I'm running v12.02 and have saved a design into a new file and want to change the sprayline offsets. It doesn't accept the change. Any ideas?
Got it fixed. Num Lock key was "on"!! Thanks.
