FVWM: Window focus cycling with 2 monitors

[Michael Fischer]

Hello all.

For about forever, I've had

Key Tab A SM Prev (CurrentPage, !Iconic) Focus
Key Tab A M Next (CurrentPage, !Iconic) Focus

and

DeskTopSize 5x2

in my configuration. So far so good.

However, with multiple monitors, each of the ten "pages" is stretched across both
monitors (which is nice) but the Alt-Tab window-cycling now only works with the windows
displayed by one of the monitors at a time. I've been unable to either google or guess
the correct config incantation to get focus cycling across windows on both the monitors.

Suggestions?

Thanks much.

Michael
