Good news,
Following a couple of days of hard work on my part, I've gotten the front page of the ProPilot system working in IE and Firefox, and looking pretty similar (only "problem" being Firefox insists on collapsing tables into as little width as it can, while IE listens to width:100% "correctly").
Can I ask for a few volunteers from the membership to test the functionality of the PP "site" in Firefox and report errors (including CSS/style problems please) here.
UPDATE: Just to start, I've noticed that the "My Flights" page in FF doesn't return your flights yet.
FURTHER: And that's "My Flights" working. Off you all go (my pretties...) and find everything else that doesn't work.
