I have CPU tasks and GPU tasks running.

When a running CPU task is stopped because either I've moved the mouse or the end of the scheduled time for running occurs, the task is actually stopped (no cpu usage) but the Elapsed Time continues to count up.

If the task is Waiting to Run then the Elapsed Time doesn't count up.

This happens with any project that has CPU tasks. The GPU tasks are unaffected even if the same project is running CPU and GPU tasks.

Is this a known problem and does it have a solution.

"Preliminary Change Log 7.6.7 -> 7.6.8"

just one of the changes:
"client: fix bug where elapsed time increased while suspended."

There's also version 7.6.9 available at the end of the page if you'd like to give it a chance.

Thanks for he info.
