I'm currently using 0.11.4 (having never had any luck installing any
form of 0.12, let alone 0.13). Ten minutes ago, I was about to ask why I
had never been able to open a URL by clicking on it. Then I went to
another virtual desktop (I had Galeon 1.2.6 on one, Opera 6.03 on another
-- on Gnome under RH7.2; Gnome is 1.4 I *think*). Lo and behold, Pan had
grabbed the tab I had left opening on opera and put the other page on it!
And my default browser is Galeon! (That's to keep my email from messing
with Opera, in fact.)
