No matter what I try, the page looks the same. I've tried switching to a random format, which worked, but not switching back to the current version of the sheet format. I've named a copy of the new sheet format a different name and switched to that, but no dice. I've tried reloading, but nada. I've created several new .slddrt files, but none of them have any effect on this blasted drawing.
Anybody else dealt with this?
