EXS 24 Logic Sampler Users Group

hi,

i've been using an apple pro keyboard with my powerbook which 
has the "+" and "-" keys on the extended numerical keypad (the 
group of keys on the right, whatever technical term that enjoys;). 
when i have an exs onscreen these keys affect whatever control 
the mouse was last used on provided it was an on/off button - 
unison, edit, fat, etc. is this a hot key? i've been into key 
commands and they're not assigned (indeed, while in key 
commands the "+" and "-" do strange things in there too).

anyone shed some light? particularly if there's a way to turn this 
off please...

cheers.

andy.
