Cursor focus problems

I am running into a problem where every time an email comes in, the window I’m developing in loses cursor focus, and I lose part of what I typed, or, worse, the copy-paste operation I ended up performing mid-focus-switch occurs elsewhere than intended. I am on Notes Designer 9.0.1 FP2. Is anyone else running into this problem?
