OK, guys. Here it is. This works because I have done it.
If you own any Hyperdesk themes, you can install on XP , or whatever OS you have Hypers for, then you take the theme file it creates, and convert to WB using MSImport.
Then, you can use via WB.
Now, where to get the MSImport app is another topic. I have a copy from long ago. Dunno where it can be gotten.
