fvwm ignores clickToFocus for function keys

> When typing in an in-focus xterm, but the mouse cursor is elsewhere, if I hit a function key, the programmed action does not occur. Instead, something else occurs, which I cannot identify (involving insertion of characters and/or other actions). When the mouse is positioned directly inside the window, the programmed action occurs normally.

I keep discovering new things about this problem. I'd said previously that under linux this did not happen. Not quite true.
It turns out that it happens if my mouse is positioned over xterm's scroll bars!
If the mouse is over the in-focus window, or any other window, or the root, the function keys work properly. But if the mouse is positioned over the scroll bars, it sends garbage!
Furthermore, I just discovered something even more interesting - if the mouse is positioned over the title bar, the cut buffer gets modified ... uh oh, this is starting to sound like a configuration issue... but that was all on linux (suse 10.3).
On cygwin it's wrong whenever the mouse is not over the in-focus window.
