I have a colleague who is having some issues switching between viewports in paper space. When he has two viewports in one paper space he will click on viewport #1 do his work and then double click off to the side to close the viewport. then when he tries to access viewport #2 by clicking on viewport #2 it opens viewport #1 and vice versa...I originally thought it was the SPACESWITCH system variable but that did not seem to do the trick, even though it was set to 0 when i checked it. I changed it to 1 and it is still doing what i have described above. Any thoughts? I am all out of ideas.
