My system is running Windows 8 x64. My BOINC is 8.0.4, and is not running as a service.

First quirk.
When I click the BOINC Manager icon I have on my desktop, a small box appears saying...

"Another instance of BOINC Manager is already running."

... but searching the list from the task manager, I can't find such an instance.

Second quirk.
Since BOINC started, I have had the habit of having the manager open in the upper left corner of the screen sorted by CPU percentage. It typically is showing the BOINC jobs clustered at the top of the list using 12...% CPU each. No surprise. Sometimes, however, I find BOINC Manager at the top of the list using 50+%. When I see that, I stop and restart the manager and things return to normal. I do not spend 24 hours a day watching the screen however, (my wife might disagree with that...).

I suspected a trojan/virus and did a deep scan with BitDefender which happily tells me, (eventually...), that my system is clean. I am holding off starting BOINC manager at the current time.

Comments or suggestions welcome.

I also get the message that another instance of BOINC manager is running when it is not. I am running 8.0.4 in Tiny10 a cut down version of Win10 in a VM. I don't know if this is a quirk of 8.0.4 but suspect the message is due to a file not being deleted when BOINC exits. If in task manager I see BOINC manager using an excessive amount of CPU I click the > to expand the list of BOINC tasks.

When this happens to me I don’t get said message but the file is BOINC-xxxxx, a 5 byte file in root on windows or in user home on Linux.

I know about the Linux one and it stops the manager from opening up. This behaviour in Windows, the manager and client still open but the message about another instance appears.

I've started BOINC Manager again to see what it says if I get to the point where the quirk appears.

I let the manager run for a while this morning to see what was happening. Sure enough, the task showed the manager using a high percentage, about 60%. Clicking the arrow, I could see the task "it was running" was a collection of some of the BOINC tasks that were running. This seems to be a new "feature", a feature that I do not like at all, but can see a point, when new CPU chips have many cores, (more than mine for example). Is there a simple way of turning it off?
