Using Beta (evaluation) program, great Apps!
I have found something that might be a bug, or just my lack of skill
1) I create an opacity map which I then take to Photoshop to be painted with white to cover areas of transparency I do not want to apply.
2) Once photoshop editing is done, I save the file in same location.
3) If I try to open (add) file to bring it as part of the source file list, even though I see the file on the OPen/Add Image window. When I click on the open button, the file does not get added.
What am i doing wrong
