[LDCad] LDCad problem with graphics card driver, linux

[Roland Melkert]

I'm not so concerned with the tk warnings - don't spend any effort getting rid of them on my behalf - I only mentioned it in case it might have provided some clue as to what was happening with the text boxes.

I want to get rid of them because some other code might be having troubles handling zero sized dialogs too, causing the crashes you're having.
