RC1 issue with mouse() function

[MacGuy]

Can anyone confirm if this is a bug, or perhap-s an issue on my end?  I 
find that the mouse() function returns true no matter which 
"mouseButton" is pressed.

I'm using Mac OS X 10.2.3 and RC1.  A simple mouse click should be the 
equiv of mouse(1), however the following script:


on mouseDown
   put (mouse(1) is "down") & comma \
   & (mouse(2) is "down") & comma \
   & (mouse(3) is "down")
end mouseDown

returns: true,true,true

the ctrlKey was not down (for a mouse(3) to be true under Mac OS), this 
was just a mousedown
