On a layout Tab I have two viewports. In Model space I zoom in where I what the image to be. When I go to the other viewport the image zoom to what appears to be zoom extends in the first viewport. I can get around it by locking the Display lock on the property set of the viewports I can changed first. Then change the 2nd viewport and then lock it. Another templete we set ups work where you don't have to do all those extra steps. Not sure what setting is different. any help? Thanks.
