Can't stop a scheduled scan

I have my machine set up to run a scheduled In-depth scan every day at 4pm. Yesterday I tried stopping the scan, but ESET refused to stop until it completed. You can see here that I pressed the "Stop" button as it's now greyed out, but ESET still says "Waiting to complete scan" and refused to quit until finished. I'm using version 3.0.621.0

ESET should make a civil way to stop it (such stop wasn't present in v2 NOD32 , too) . Anyway , a temporary solution is:

Thanks, that does work for when it refuses to quit on it's own. I hope this will be fixed soon as I'm doing a trial for my company, and when I need it to stop scanning because I need 100% CPU power, it needs to stop. Most of the employees will have no idea about that "workaround", and will just expect it to work.
I do love how quick ESET responds and doesn't slow down my computer at all, but it should listen when I tell it to.
