Hi all,

I recently re-downloaded BOINC after formatting and installing Windows 7 32-bit on my PC.

I had BOINC running at 100% for the day while I was out at work, and then came home to play some games, quitting BOINC before I started playing (as I usually do). However, I noticed while ingame that my FPS was dropping lower than usual, and my CPU cores were all at 100% still.

I alt-tabbed to see if I had, in fact, quit BOINC - which I had. However, a quick look at the task manager showed that the four tasks BOINC had been running (all World Community Grid ones) were still running, even though I had quit BOINC. Manually closing these processes did not solve the problem, as new tasks appeared (and manually closing them, as it turns out, fails the task).

A reboot took care of the problem, but I'm not planning to open BOINC again until I figure out what went wrong.

Has anyone experienced the same problem at all?

Yes, there have been plenty threads about this topic.

There is a general misunderstanding concerning the BOINC processes. If you say you have closed BOINC, you indeed have only closed BOINC manager and not the client, which is responsible for running the project applications.

You are right insofar that normally closing the manager also closes the client, unless you installed in Protected Application Execution mode (formerly known as service mode). However, some newer versions of BOINC fail to do so. In that case, the easiest way to close BOINC completely is to select Advanced/Shutdown connected client... from the advanced-view menu.

The newest version (6.6.36 I believe) should again behave as expected.

The version I am using is 6.6.36.

I assumed I would get the same behaviour I was getting on XP with a previous version of BOINC, but thanks for the workaround.

It's just VERY counterintuive to close what looks like the host process and have it's children still raping your CPU cycles.

Turns out that workaround doesn't... well, work.

It prompts me for a new host to connect to, and then fails to stop the processes when I don't provide one.

Seriously if this problem isn't fix I'll have to just stop using BOINC, which would suck because I LIKE using it.

Of course you have to cancel the dialog if don't want to connect to any host (that's quite intuitive for me).

Select BOINC manager->advanced view->Advanced->Options.
Check the option "Enable manager exit dialog"
When you exit the manager, you get the exit-options box. There check "Stop running science applications when exiting the manager"

Should, Could, Would, but it does not. Still need the menu workaround. Very sometimes it seems to do it after 1 to several minutes. Not on my Vista box, and we were so hopeful after 6.6.31 ;>)

That's why I'm still happy with 5.10.45 and 5.8.16 :-D

'Cancel' implies cancelling the entire operation, it's a poor UI design.

In any case, clicking 'Cancel' has the same effect (i.e. none). I still had to manually close all the boinc processes using task manager.

Thanks for mentioning that dialog though, it seems to be working, although it takes a decent length of time to shut down the processes (something it never did with previous versions of BOINC). Where can you download older versions, anyway?

New, stranger problem:

I use Synergy to control my Macbook using the mouse and keyboard plugged into my Windows 7 PC, and it works perfectly except for when I have BOINC running.

When BOINC is running (seemingly related to the amount of CPU cycles it is using), the mouse cursor on my macbook is extremely slow. Not jerky, but as if the mouse sentivity has been reduced.

I never had this problem with an earlier version of BOINC and on XP.
