The only sure fire solution, that I've found, to fix those annoying little things is...
1. convert the dropshadow to a bitmap
2. save that bitmap as a TIFF or preferably a native Photoshop File (PSD)
3. Open the file in Photoshop
4. Using the healing tool click on the top of a line
5. Hold down the CTRL key and click on the bottom of the line
You should see a perfectly straight brush stroke shoot down the image and presto that line is fixed. You might have to fiddle around with your brush size and edge settings but I've found it works best when I slim down that brush until it barely covers the white line.
6. Repeat for every line as you move down the image
7. Save your image as a Photoshop file (PSD) which preserves the transparency effects for Corel
8. Import the fixed image back into Corel
Good Luck!
