No Dashed-Line Box When Using Arrow to Select a Model, Etc.

[BSquared18]

EDIT: After googling, found that going to Windows --> Preferences --> OpenGL and unchecking Use Hardware Acceleration solved the problem.

Hello,

I have SU on two computers. On one, when I use the arrow and left mouse button, I get a dashed line as I create a box to select a model or portion of a model.

But on the other computer, the dashed line does not appear, although the model is still selected.

I couldn't find a difference in the settings between the two SU installs.

How do I change the settings to make the dashed line show up?

Thanks,
Bill
