I have, had that happened to me as well, I believed it is due to system bottlenecks, so this is what I did.

One thing you can try to speed up performance a bit, it

A>) Turn all gfx down to minimal setting on the clones
B>) Turn all sounds off on Clones.

The main should be ok to have you're normal play settings running, Since you're not really playing the clones, well in a sense of staring at their screens all day, there is no need for the extra resources to be used to make it look it's best nor do they require any sound.

Try that and let me know how that works out for you.


Wolviex:
I built the script around my UI mods, but it should work for any keys assigned to those keys, Shift, Alt, Control modifiers included. If it helps I use Bongos for my hotbars, It allows up to 120 hotbars, but i no where nearly use that, 10 is fine for me at least for now. Bongos allows you to assign hotkeys to any slot on your hotbars, which is cool so your hotbar could look like this.

1 3 2 4 8 7 5 6 9 = - 0

But that is an example, mine actually look like this.

Misc bar5
Misc bar4
Misc bar3
Misc bar2
Misc bar1
Cntrl 1 2 3 4 5 6 7 8 9 0 - =
Shift 1 2 3 4 5 6 7 8 9 0 - =
1 2 3 4 5 6 7 8 9 0 - =
