Why do I have display problems

[Randyman]

 When I open properties dialog box it looks like the picture below. I'm also getting random crashes while editing block diagrams.

The over-lapping text for that selection box is a bug I think tst reported.

The grey spottiness maybe your grpahics card accelleration setting.

Random crashes (if not due to video driver settings ) warrent trying to do a Repair of the LV install.

As ben as suggested this looks like lv has got currupted. When we faced this re-installing lv fixed it.
