Out Of Memory errors

Since installing the recnt version of Comodo, I have been getting Out of Memory errors off and on …even when available physical says over 300K left.

When this occurs , I am unable to kill the CPF program/process with Process Explorer and am forced to either logoff or restart to fix the problem.

The OK dialog displayed by the program does not appear to do anything and the CPF program says not responing within Process Explorer

Any comments, etc ?

COMODO 2.4.17.183
