just replying so I can keep track of the solution for later use
2of3: Will post a solution here, if I can ever find one. Thanks!

alphabyte,I had an issue with one of my skins being seen as a UIS1 skin by SKS5. Here's what I did to correct it (not sure if it will fix your issue but it may be worth a try)In SKS6,clean the skin (Tools/Clean Skin), then make a WBA package (File/Make WBA Package), switch to a different skin in WBconfig, then delete your problem skin in WBconfig, then find the WBA package that was created earlier and doubleclick it.This will put your skin back into WBconfig; change to that skin and then try the settings as noted above to turn off the shadow.I had put in a support ticket for the above problem, but was told SKS5 wouldn't be developed any longer (although it was SKS6 that apparently changed my skin to a UIS1) so there was never any investigation into why SKS6 'made' my skin into a UIS1.
pictoratus: Thanks for this suggestion. I will try it out and post later tonight what happens in my case. Thanks again for all your help!

There is no good reason to start an XP skin in SKS6.I know its work but try STARTING the skin in SKS5.(either from scratch or from another skin that already works right)
IR: I will try your suggestion as well. I will post later tonight what happens with this approach. I don't mind the extra work, especially since this will give me more practice with Skin Studio in general (and I certainly could use the practice). Thanks for all your help as well. Much appreciated!
