Hi Juliette, I've enabled the JIT column in the profile using the SETPREF command, however on OSX 10.6.4 running R2010b the profiler column title is actually 'unjitted' and the X (indicating an unaccelerated like) isn't an active link and it won't let me click to see why the line was unaccelerated. Thanks for your insights, -Cody
