After my recent installation of Object Desktop my computer began freezing up and doing nothing (as if it is actually doing nothing or is interrupted to such a degree that nothing gets done).  When my computer freezes, I press Ctrl-Alt-Del and the Task Manager itself at first seems pegged at a very high level, but quickly drops down to a minimal level (no other tasks are displayed at any time). 
I can then return to work for a short while, but the computer soon freezes again.  I don't know what that means, because I didn't do anything to release it.  All I did was look at the Task Manager.  I had installed Start11 and Windows11, but had not used them.  I uninstalled all three programs and my computer worked perfectly.  I will try a reinstall today and see if I can duplicate or expose the problem.
