Running version 6.1 and we are having a new issue that has started the 3rd day of tech. we have the System error message "A new guard page for the stack cannot be created" pop up mid cues multiple time during out rehearsal. The content of the cues does not seem to matter (video or image) and this error appears. Pressing Ok and the 'X' shuts down the program and we need to restart the program. this issue has happened 7 times in the last 1.5 hours. does anyone have a solution or a reason for this issue to be so prevalent out of relative nowhere?
