Print Dialogue Freezing

Not sure what s happening here today.

When I go to print anything, the print dialogue freezes with "Nothing is selected to be printed" stated in the print preview window. If I leave it for a few minutes, it eventually loads the preview, but it's far too long a time to wait for it every time. I've tried re-installing printer drivers, switched default printers, printing pages different sizes, printing old documents, printing new documents, repaired CorelDraw installation, restarted computer several times, and am about to throw the kitchen sink through my monitor. 

It wasn't doing this yesterday. It just appears to be struggling to load the artwork information into the print preview screen for some reason. 

Any clue what's going on? Or how to fix it?
