If Summation Enterprise column view is open and it is in EDIT mode, the Enterprise process (SummSSE.exe) will slowly grab more and more memory.
Then, if the Enterprise interface is left running, with the column view window open in EDIT mode, the Enterprise process will eventually use all the memory on the workstation.
Workaround: In the column view, toggle out of "edit" mode, or close and reopen Enterprise.
This is a known problem that was never resolved.
Summation Enterprise, all versions.
