I'm switching from Corel Draw Suite for Windows to Corel Draw Suite for Mac (Studio). I'v followed all the Help threads I could find, including on-line help, but I am unable to make the Merge Source function (PhotoPaint/Effect Tool/Smudge/Brush Settings/Dab Attributes/Merge Source) work as it did in Windows ie. smudge between/across layers.
I know of no one that has had real warm feelings about the CorelDRAW Graphics Suite on a Mac. I wish I could help you, the only Mac user I'm sure that I know doesn't us Photo-PAINT.
