In the 'annoying but not devastating' category:
PgS 5.0.4.3, on an Ubuntu 7.04 (Gnome desktop) system with current
updates, fails to close cleanly from the 'PageStream5' control panel
window 'X' button. All other windows close, but this one can't be
gotten rid of without using the right-mouse-button 'X - close' menu
item *and* a left-button click with pointer on the notification that's
left in the bottom-of-screen taskbar.

FWIW, the 'half-missing-display' bug in the 'Type/Insert/Character'
menu-called panel, reported for 5034, is still present as well.
