If it's nitpicky stylistic issues you're after.... The X icon at the top left of both the About... dialog and the Cygwin/X Exit? dialog is different to the X icon at the top left of other programmes' windows, such as xterm. The one on the about and exit dialogs is a little uglier than the other. I can provide screen captures if you want to see this.
FWIW, I agree with all Jack's suggestions, especially copyright/version info, links to docs on the start menu. But I think I'd much rather you spent your time fixing the clipboard bug before worrying about such minor things. Lev
