First Question: When I'm viewing the cameras live I can view them in multiples like 2x2, etc but I can't just view one camera enlarged. The screen just shows blue but has the camera name at the bottom of the screen. But when I view recorded footage I can view just one camera enlarged. I'm currently running version 4.5.0.0 Second Question: When moving to a new version of the ISIS software do I have to remove the old version or do I just load the new over the old? Thanks for the help
