99.9% of the time, when I'm going to EDIT a pdf, its just to resize or crop it, not to change the content. But I have to wait for the OCR processing to complete before the crop tool is available. I shouldn't have to wait for a feature I'm not intending to use. Especially if I'm working with CAD drawings or other non-MSWord source files, the OCR processing takes forever, since the content isnt designed for that.
