Earl,
      
The issue as described to me by Omega Tech Support has to do with File
Selectors.  I don't know if these are the same as "Handles", but I seem to
recall that they might be two different entities.  
      
The "Selectors"  have been discussed on the list before.  There are about
7200 of them available after a fresh Win-95 boot and they are depleted quite
rapidly by TS and its charting program.  I monitor the selector pool with a
program named WMEM.EXE.  If I am using too many resources and the pool drops
below 1000, I know I'm headed for a crash.
    
Since NT runs everything in an isolated partition, my question is whether or
not the selector issue still applies to NT.  If you or anyone knows the
answer to this question, please post it.
