I am using Windows7 and ID CS5. I have discovered that having more than one drop shadow causes ID to redraw the entire page after every action. Move a text box a fraction of an inch and it redraws everything. This usually takes between 15-20 seconds to do. Has anyone else had this problem? I have 24 gigs of ram and dual video cards @ 1gb memory each and not sure why the drop shadows would cause this type of problem. Other than doing the layout and then adding the drop shadows at the end, any other insight would be appreciated.
You can check these settings:-
1) Turn off the preflight from the Windows-->Output-->Preflight
2) Change the Live screen drawing to "Never" under Edit-->Preferences-->Interface
3) Change the Display performance to "Typical" if it is set to "High Quality" , under View-->Display Performance
