I am using AutoSketch 8 (with a few added macros) on Windows XP Pro 2002 SP3. I have been using this setup for years and have just come across a new problem. I was working away when, for some reason all of the control boxes or 'grip points' just disappeared? All icons that appear around the selected entity have vanished, including the green boxes, green triangles, blue rotating arrow, grey outlines, everything. Also when I select text to edit, as soon as I zoom in the text disappears. All snap points have gone as well. When the drawing is first opened, all the points are there but as soon as I pan or zoom everything goes. Everything is still there and still works it is just invisible and makes it almost impossible to work with. I have included an image showing what is happening as it is hard to explain. I have tried everything I can think of with no luck. The next step is to reinstall, however as I have customised AutoSketch a fair bit this will be a major pain for me. If anyone can help, it will be greatly appreciated. Thanks.
