For loop error

1
I have a for loop which should work fine.

Basically in this loop I draw the same image over and over using DrawTexture.

It works fine on the first run through the loop, but any subsequent runs give me this error:


error
INTERNAL PSYCHTOOLBOX ERROR
error: PsychError_InvalidWindowRecord
general description: An Invalid window record was referenced.
module name: Screen
subfunction call: DrawTexture
file name:
/Users/kleinerm/projects/OpenGLPsychtoolbox/trunk/PsychSourceGL/Projects/MacOSX/P
sychToolbox/../../../Source/Common/Screen/WindowHelpers.c
function name: PsychCheckIfWindowRecordIsValid
line number: 97
??? (null)

Error in ==> FinanceGame at 218
Screen('DrawTexture', w, probe.imagetex, [], probe.sRect);



Can anyone shed some light on what the problem might be?

The error suggest you may have closed the texture after the first run through.
