Thanks basj.
As an ordinary user, I don't know how to and I don't want to edit or create skins (I would have done if at least there was any documentation on skinstudio, but fact is when it comes to user documentation/manual, stardock sucks-i mean look at all stardock apps, not a single one has decent user guide). I want to be able to use skins out of the box in WB or there should be a setting in WB to enable this shadow feature. It is ridiculous that stardock is essentially blocking a paid app (ShadowFX) by another of their app (WB). On top of that, I am using a skin preinstalled by WB, so at a minimum those preinstalled skins should automatically have this shadow on window frame graphics for the end user to use. I am not happy about this at all.
