I want to show you a cool magic trick with this buggy software. Try to crop this image using the crop tool only in CorelDraw without any modifications and whatnot. You can't can you?
NICE.

I think that the Crop tool may not work when non-destructive effects are in play.
If you flatten the non-destructive effects, then Crop can be used.
Alternately, you can "visually" crop the bitmap - without actually discarding any of the content - by dragging nodes with the Shape tool.
I'm not apologizing for CorelDRAW here; just reporting my observations.
