I am trying to get Mouse click broadcasting to work reliably with keyclone in order to make use of AOE spells on my team.

My setup is 5 toons, one PC. I have my main full screen with maximizer, and the other 4 toons setup in 4 quadrants with maximizer. I have enabled mouse click passing, using cntrl-F9, I then hit a separate key to select the spell and open targeting reticle, and finally have the ] key set as my Left Click.

The issues I am having are:
The ] key will not act as a left click, in fact it does nothing, no matter what I do. I have made sure it is not mapped to anything else. I have also mapped several other keys as Left Click, but still nothing.

When I hit Cntrl-F9 to enable click passing, I hear the notification that it is enabled, and hit my AOE spell key that passes to all toons I want to AOE (Blizzard and Rain of Fire) Then I will left click, with mixed results. Occasionaly it will cycle through all the alts windows, left clicking, and the mage and lock will begin casting AOE, and then I hear the notification that mouse click passing is now off. Perfect. More often than not however, nothing will happen, at which point I will click several more times, with mixed results. Sometimes it will just cycle through 1 or 2 windows, then stops, sometimes just one window, but click does not appear to pass as the AOE spells do not start.

Also, I see 4 small white rectangles appear on the screen, in a square pattern. Does not seem to be game affecting, but is annoying nonetheless. They obviously have something to do with keyclone, as I can click on them and a notification that keyclone is not responding appears.

I have tried this with "focus follows mouse" on and off, but makes no difference, as well as "click once then off".

I have not been able to find a detailed setup guide for using mouse click passing with keyclone, although from what I can see searching on these forums, setup is fairly straightforward.
