| 
| Yeah, I'm on UNIX. I haven't really messed that much with the URL
| opening yet, but this is how I have thought it should work:
| 
| common_browsers = ['mozilla', 'netscape', 'lynx', 'w3m']
| 
| for browser in common_browsers:
| 	if not os.system(browser + URL)
| 		# found browser
| 		break

Running netscape this way will fail if the user is already running it;
to get around this you can check if it is running (using the output of
os.popen("ps ax")) and use the openURL command if it is.


| But the thing is that I haven't used your URL inserting, because
| it won't work in my application. I did however use the same code for
| tagging the URLs.
| 
| So for me doing this will only return the name of the tag for me:
| 
| URL = textwidget.tag_names("@%d, %d" % (event.x, event.y)
| 
| URL will be 'url' after this call. The last braces [1] that you use doesn't
| apply to my code since I haven't used that insert code you did, right?

Right, you'll have to read the text directly from the widget itself.
You won't even need to use tag_names in this case.


| Now this is what is driving me nuts, it should be so simple but I just
| can't get it to work! If you want I can send you my code so you can
| look at it.

You could even post it so that everyone could look at it :)

| 
| Aha, that I can do.
