FVWM: Trouble with transient windows

Hi,

I suppose I'm having trouble correctly understanding the options for transient windows. Here's the scenario in which I'd like fvwm to behave differently.

I have 3 windows on a page: emacs, a pdf viewer, and ipe (for drawing diagrams).

Ipe sometimes pops up a little window (only borders, no titlebar or buttons) that says "Waiting for external editor" (meaning emacs), and grabs focus.

I have to manually focus emacs before I can type anything. When I quit emacs, the above window goes away. Its place is taken by another "Compiling..." type window -- again, only borders, no titlebar, and this grabs focus for its brief lifetime. When it goes away (almost immediately), none of my windows has focus.

I would like the transient windows to not affect focus at all. I looked at the manual page for the FPGrabFocusTransient, FPGrabFocusTransient,  FPReleaseFocusTransient, and similar options, but I couldn't figure out what I need to do to get the behaviour I want.

Is this something that I can take care of within fvwm? Or should I ask the ipe developer about this?

I'm using 2.6.7-3. Many thanks for any pointers!
