How do you do that?

I've been using the webbrowser module to open help files for my python 
application, but it has several problems. If the user already has their 
browser open in another "desktop" (unix users seem fond of switching 
between lots of desktops), then the help opens there instead of the 
"desktop" that has the current app. Also, I really need to call 
webbrowser in a thread, because it takes forever if the web browser 
isn't already open. (Also, it's not safe to ask for file://...#anchor 
urls; some OSs handle it, others do not. I ended up writing code that 
retries without the anchor.)
