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

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?

Even if I try [0] it doesn't work.

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.

Aha, that I can do.
