very frustrating. i wish i could work on your machine to solve it. on my machines, the non extended keys work fine. hmm.. are you using a standard english style keyboard or foreign language set?

no router changes should be necessary, so long as they can connect and pass ping information, your networking should be ok (they would timeout and disconnect otherwise, or just never connect)

i put various symbols on the clones to help understand what they are doing. its mostly experimental, but i've found them useful. this is what they standard for now:

'*' currently active clone
'!' not passing mouse information
's' suspended
'-' only allowing hotstrings

i may be removing the mouse info in the next build. (it needs more debugging, especially with wow)
