I had slow performance on Pip for a while, I did the following 3 things ... added another 2Gb (only really got 800Mb though but had them so I put them in), moved from 5 independent wow folders to 1 on its own and 4 using the same DATA folder (huge improvement) and had WM Player (not playing anything) running in the background (to change the media load interval)

Hey Rob, could you add that feature to Keyclone?

I now have sub 1 second switching between instances and with the following macro it is awesome (although the leader announcements are getting tiring)

Code:
/focus [nomodifier] Ashanav;[mod:shift,mod:ctrl]Ashanaw;[mod:shift,mod:alt]Ashanax;[mod:shift]Ashanay;[mod:ctrl]Ashanaz
/script PromoteToLeader("focus")
This macro is bound to the \ key my G- keys and PiP are configured as follows
G1 - \, Big(1538x1220), Ashanav
G2 - shift+ctrl+\, 1st (384x300), Ashanaw
G4 - shift+alt+\, 2nd (384x300), Ashanax
G5 - shift+\, 3rd (384x300), Ashanay
G5 - shift+\, 4rd (384x300), Ashanaz

so I get the party focus made party leader and their instance taking up the primary slot in PiP all from a single press... it Rocks!
