My architectural office uses multi-sheet DWF files to allow those of us in the office without AutoCAD to view sets of plans. When I click the Print button to print a sheet from the multi-sheet file, it takes 15 to 20 seconds for the Print menu to appear. Is this normal, or is there a setting somewhere that needs to be changed? I just installed Version 5.1 and this also occurred when I used Version 5.0, but the Print menu appeared almost immediately in the version prior to 5.0.
