yes, these are known ones, I think pretty much everyone on windows OS gets them often, everytime you close the PS client check task manager to see if the thing is
really gone

I had the equivalent of 6 clients going once, 4 were intentional, and actually running, two were previously closed ones that did not terminate.
I haven't had the latter error personally, I think thats when running full screen, but then again, my client has crashed a few times randomly, i don't read the errors anymore though ^^
