[Freesurfer] qdec X error of failed request

Hi, Running FSv405 on RHEL5. Recently obtained new error when qdec was attempted. Have successfully run qdec before on this box using FSv405. Only update made was to upgrade to FSLv412. Same error persists after restarting X. Both tkmedit and tksurfer work fine.

Any ideas how to fix?

Many Thanks, Jenifer
