When using the scroll wheel on my mouse to zoom in or out on a drawing, the symbols disapear, leaving just the grid. If I click the zoom to drawing button, the symbols reappear. I have to use the zoom buttons, or zoom window to perform any zoom functions. Any ideas?

Changing the monitor location in control panel did in fact fix my problem. I will be looking forward to the update. Thank you so much for your help. It is nice to work with a company who cares.
