On the main window, if you click on "Information" in the quick-search bar, the dialog that comes up sits on top of the main window but is completely inaccessible using mouse or keyboard. This is unlike other dialog box problems (http://www.thewildbeast.co.uk/claws-mail/bugzilla/show_bug.cgi?id=2774) where the dialog box is still responding to keyboard/mouse events and hitting "Esc" key closes them. The "Information" box at this point can only be removed by exiting claws-mail.
The problem is different but existing with the Linux version: open and close that Info window, and the rest of the windows (like Compose) are unusable after that.
with xfwm4 at least.
Colin, 3.9.0cvs10 seems to have fixed this bug.
