Copying with trackball

Using most recent software and libraries for WH3 and Hog3PC...
I can't seem to get it to work. I've tried selecting the fixture numbers, right click then choose "copy" and then selecting another fixture and right click again and choosing "paste" and...nothin'. I tried the same action with one parameter on a WHIII (intensity) and...nothin'. I tried it with hue on the Hog3PC and...nothin'. Is it me? I've tried just highlighting a single parameter, a range of just one parameter down several fixtures, the whole fixture including fixture number, etc. and not once has it pasted. Sometimes the "paste" option in the window which appears after the right click is grayed out, but that's the only indication anything is happening.
Now, using the actual copy button works fine but that seems to copy all the information for a whole fixture to another.
Any ideas? Did I miss a post which explains this? Am I a relative of that famous French writer, last name of Dumas?
