Hi Doc,
By OPX i assume you mean OptionsXpress.com the basic HTML based web site.
I usually refer to it as Ox (out of habit) so just checking.

No problems, have been logged in since about 5am.
BUT ...
I use a dedicated computer with nothing else running except Windows Task Manager to monitor memory usage (more habit than an issue).
Is a laptop running XP, SP3 with 1 gb memory.

If you are also running a browser such as IE or Firefox on same computer to look at TFC you can eat up memory. I notice recent updates of Firefox are getting "piggish" and not freeing up memory after you close things.

Try closing all, shut computer off and re-boot (not restart) and start over if still having problems.

Enough here, write back if still having problems.

I know if you get "short on memory" or your Internet connection bogs down things can hang up. Manly the Java software supporting the real time data screen and/or streaming charts can lock up.
