Different db's in one frameset : what's your experience?

Is it just me, or is this a common thing:

Whenever I display (elements from) different databases is one frameset, Notes becomes unstable and crashes very often. I cannot give you an exact reproduction scheme, but here’s an example:

Let’s say I have a frameset in a db, in the left frame I show an outline (embedded in a page) with links to different views in different databases. In the beginning it works as it should, but after clicks to display the different views, Note crashes. Mostly when I had opened a view form another db, and then returned to a view in the db that holds the frameset.

This does not happen if I open only views in the same db that holds the frameset, and I can avoid the crashes by opening the views in other db’s in a different frameset. It occurs in 6.03 as well as in 6.5.2.
