Can't abort many tasks.

[hucker]

I wanted to abort many tasks on my computer in my holiday home before I left it for 3 weeks, so I selected all the tasks and right clicked and abort.  Then it says "you cannot delete a filter this way" - I wasn't trying to!

It only goes wrong if the selection includes a collapsed groups of tasks.

Then when I tried to expand more than one collapsed group, the screen goes blank and I have to restart boinctasks!
