Way to clear all Internet Explorer memory within a script?

There is an patch for TC (CC-5019) that will fix this. We were having the same problem with memory inflation in IE and after we installed the patch, the issue was resolved. If you are using TC11, you can request the same patch we did.

See here for more info, this is a known issue on all browsers:
