Insufficient frame/frameset handles

Two users, been upgraded to 8.5.1 via a clean install on their desktops. Mailbox and PAB upgraded to 8.5.1 template as well. On Windows XP.

When these two users open their email boxes on the server in the mornings, they get: Insufficient frame/frameset handles with an OK prompt, that won’t go away no matter how many times you click it.

they have to kill Notes via task manager, and restart Notes, then is fine for rest of day.

I found this: “try renaming the Notes data files: cache.ndk, bookmark.nsf, and desktop6.ndk” http://www-01.ibm.com/support/docview.wss?uid=swg21236580

which I can try, but that it’s happening to two users makes me wonder.

Other users unaffected.

Subject: Popping up all over

This error keeps popping up all over at various clients sites; got some people muttering about going back to Notes 6.5 which was solid as a rock for years.
