EXS 24 Logic Sampler Users Group

When selecting a few times the "Next EXS Instrument" via the button on the right of 
the selected instrument name on the EXS window, or via the shortcut key (you have to 
assign it first in the prefs), Logic crashes (quits unexpected).

The bug showed in Logic 5.5 but is still present in 6.1.

In version 5.5 and 6.0.0 Logic quits unexpected.

In version 6.1 Logic is blocked and you have to use "Force to quit" (sometimes the 
"Try to save your song" dialog appears).

I am exclusively using Mac OS X, so I don't know if the bug appears under OS 9.

Did any one noticed the same ?
