With the svn 7809 version of the plugin, bracketed links like google
are displayed as "blue links", but with firefox 1.0.7/XP there is no way to see the value of the link when the cursor is cliked on the link (on the "google" blue link). With IE, the link value is displayed in IE status bar at the bottom.
I would suggest that the link value could be displayed in the new kupu status bar that is at the bottom of the kupu frame, and used for the moment for image uploading status.
This works fine in FF 1.0.4, FF 1.5, and IE 6 - You must be seeing a bug in FF 1.0.7. I don't see any point in trying to work around this limited case.
