Could guess what you see, as I occasionally see something when the client is remotely connected, so ideally a screenshot would be welcome and a description of the system and whether the BM is minimized or expanded on screen when this *randomly* happens.

Yes, exactly what I see. The comms between the manager and the core client is somehow slow or impeded. I see this mostly when remotely connecting and being patient for a few seconds it usually succeeds. Hit the Show Active Tasks button and it should mostly not appear again... the trouble caused by yourself. Large amounts of tasks queued, which is why that button was added in 6.6 or 6.10. The BM sucks at refreshing, so another reason I mostly use BOINCTasks tool and get a multiclient view as a bonus.

edit: impeded

PPS, I think this warrants a quick FAQ addition. See this observation more often. We run the client but don't do the RTFM to learn about the interface (were it not that the official Wiki has yet to be updated and me having only 6 hands http://boinc.berkeley.edu/wiki/Advanced_view ;-)

Yeah right, that I heard too elsewhere but the BM still connects to that core client to learn about the state of affairs ;-)

Let us know and if the problem has gone away please mark the opening post with [RESOLVED] in the title. Obviously sizing down the queue will fix it too, which I suppose will happen by itself once your clien(s) have worked thorugh those zillion in progress.

cheers

Second suspect is the security software impairing the BM <> Core client comms over RPC localhost port 31416 (think I wrote that before today). ZoneAlarm and Norton are baddies in that department. You rally don't need the BM... as said, I use BOINCTasks.
