A Problem With Prioprity

1
Hi,
I recently Updated my PTB beta version and now all my
previous programs that had the priority function do
not work. I also tried the MovieDemoOSX and it also do
not work. When I take the Priority(9) or Priority(0)
out of the program it works well. the error message is
as follows:

INTERNAL PSYCHTOOLBOX ERROR
error: PsychError_internal
general description: Unspecified error, probably a
Psychtoolbox bug
specific description: Failed to convert the
"machineName" field CFString into a C String
module name: Screen
subfunction call: Computer
file name:
/Volumes/ColorShare/ToolboxesUse/PsychtoolboxOSX_trunk/PsychSourceGL/Source/Common/Screen/SCREENComputer.c
function name: SCREENComputer
line number: 432
??? (null)

Error in ==> Priority at 334
c = Screen('Computer');

Error in ==> MovieDemoOSX at 217
Priority(0);

Does anybody have any Idea what is the problem? My
Programs worked well before I Updated the Psychtoolbox
nd now there is this error that breaks all the
programs.

Bests,
Maryam.
