Ctrl+Alt+Del? That's the shortcut-key command since years, if not a decade+ to bring up the sign-in/out screen of WNT/W2K and higher. Just tried it, long long abandoned by self, and indeed on W7 it brings up a screen what you want to do... a shopping list of things to do, to include, wow, an item to open task manager. Thk you.

Proper fast-lane opening of Task-Manager without causing an unwanted action is Ctrl+Shft+Esc [on me Italian keyboard actually Righthand Ctrl+Any Shft+Esc.

Now on the processes, except for AutoDock FAAH and MCM the sciences active sciences consist of a stager [controller], not using CPU time and a worker, using CPU time. So if you have 2 FAHV running you see 4 wcgrid processes. For CEP2 you see even 6, but only 1 per 3 using time.

FYI: As the footnote says on the device profiles, the "On multiprocessors, at most use: 4" will only work for the specific 6.2.28 clients. It's disabled in later clients. Only the % of processors work in higher client versions... 6.4 and on. The later clients in fact have only a % processors option in the local prefs, which has often led to conflict and confusion, because some of the -around 6.2.28- clients will only take the lesser of the two values, meaning if you enter 4 processors and set 50%, you only get to run 2 jobs on a quad. Conversely, if you set 100% of processors and 2 processors, you still only get 2 jobs running on a quad. Still on 6.2... yes it works but is seriously outdated.
