[Freesurfer] kvlThresholdImage fails MacOSX 10.6.8

Dear Freesurfer,

I am using a 2 x 2.66 Ghz 6-Core Intel Xeon with 24Gb RAM and MacOSX 10.6.8

I tried running kvlThresholdImage from /subject/mri/ which resulted in the following error: ------------------ kvlThresholdImage orig.mgz /Applications/freesurfer/subjects/repeats/n10a/mri/orig/002.mgz

X Error of failed request: BadWindow (invalid Window parameter) Major opcode of failed request: 2 (X_ChangeWindowAttributes) Resource id in failed request: 0x2dc00ad0 Serial number of failed request: 7 Current serial number in output stream: 9
