Hi, folks. Something odd has begun when I want to print from sheetspace. Proper, full scale arch model in model space. I clik sheet tab and the model appears on the sheet. I use config manager to verify proper paper and printer set up for that tab, create viewport, and as soon as it is activated, a duplicate model appears. The first one is still frozen in place, the second, and I believe correct image, is move- and zoom-able. I tried setting common scales I use all the time (eg. 1/4=1) and the sheet gets real small. I enlarge it and the scale reverts back to 1:1. This  repeats .  I tried upgrading from V 1R5 to 5.2 and it didn't help. Thanks for any suggestions..W  (running win7x64)
