We have contextmenu 1.8 and keyboard_shortcuts 1.4 under RC 0.7.2 installed, and it appears that they are incompatible.
The scenario is: Once you have "used" contextmenu just one time (that is, you have right-clicked on a folder or message), keyboard_shortcuts does not respond anymore to any key.
Another issue with keyboard_shortcuts (not related to contextmenu) is that if you press the "?" key to display the shortcut help, all of a sudden vertical and horizontal scrollbars do appear and cause a sort of "flicker" because of the screen redraw. And there are some missing strings, but that's a minor issue. All in all, keyboard_shortcuts looks a bit outdated. I've disabled it for now.
But, much more important: In the middle of composing this message, I've been thrown back to the RC login screen again because of an invalid or expired session for the %&"!§?= time (see other threads). And while writing this sentence, a red "Request timed out!" at the top of the screen came up.
This all is really frustrating and anything but stable.
Is there nothing we can do about it?? <deep sigh>
Ah, THIS might be of interest (I just realized that there is an error indicated in the lower left corner of the status bar of the compose window):

Although in German, I think the message is clear. Does that tell anybody anything?
