I have 10 truck mounted netbooks running ArcReader and GPS layer. These netbooks have been in use for 3+ years and we haven't had any problems until I recently upgraded to 10.1. Version 10 worked fine. Now in 10.1 when the GPS Layer is set to "Pan to Point" the Data View goes blank. Just a white screen. This only happens whe the "Pan to Point" option is checked. Has anyone else ran into this problem? Is there a work around?
