I should have been more explicit on the behaviour I want when starting fvwm related to firefox.
I do want firefox to start in page 1 2 on my (only) desktop. I upgraded from fvwm version 2.4.20 to 2.5.23, changed InitFunctions to StartFunctions, and added the following Style line my init file: Style firefox-bin StartsOnPage 1 2 Much to my amazement, this works perfectly when I am starting up fvwm: firefox was started on page 1 2. However, once fvwm is running, every time I start up a new instance of firefox, it also starts on page 1 2. I don't want that: I want the new instance to start on whatever page I am in at the time I start firefox. Is this possible? Paul.
