If/When I open my tool palettes (for the first time in an AutoCAD session) once I pick something in my toolpalettes I get 2 of these errors pop up - Exception in AcCamera.arx ARX Command, Unhandled Exception 7C90EE18 (Access Violation Reading 0x0000) at address 5FC515h and Unhandled Exception 66 (Access Violation Reading 0x0000) at address 5FC5130Bh. Any ideas? This is happening on several workstations running AutoCAD Civil 3d 2008 with SP2. Most of the time you can continue working, however, it has crashed as well.
