Mortlach,

http://www.wowinterface.com/forums/s...4854#post54854 , Exceltica did an *outstanding* job of documenting his testing and it would appear to be pointing at a problem with empty button sets (lowbie toons) on the Intel Macs.
I think the three of us are hammering out the nitty gritty of repeatable failures and successes. Good for us all to be on the same page.
When this is all done - we all gonna have to swill some good 'warven ales!
