Mouse software installed, repeat now abysmally slow.

[MadMilitia]

Guys,

When I clean my system of any mouse software installations the repeat works fine on all slaves (well, as fine as I can expect right now. There are other bugs to see below).

However, when I run it with a mouse software installation, the repeat slows to a crawl and becomes unresponsive.

My setup:

Core I7 2600k
Asus P8Z68-V
Corsair 16GB DDR3
Crucial 128GB SSD
WD Caviar 1TB Black
Antec 900 (keyboard powered and operated from front panel, mouse from back panel - could this be the cause of some problems?)
Keyboard: G510
Mouse: Death Adder 3.5g left handed version. Have also tried Evoluent left handed version. Both software installations cause the exact same problem.

An additional bug in my setup observed:

When my squad wipes, it has been observed that clicking on the rez window sometimes causes repeat to fail in the future until I restart WoW. It can happen randomly, without ever using a slot activate key or a rollover click. When I do use a slot activate, the repeat works fine on all slaves. If I go back to the window I was in during the rez phase, the repeat still fails in the same precise locations it failed before. That is, until I restart WoW. Reloading isboxer or the GUI doesn't fix it.
