Couple of bugs:
1) Switching browser tabs does not cause URL address box to update. The URL address of the current tab should be displayed in the editbox.
2) Switching between multi-line tabs and single-line tabs causes all pages to go blank.
The "New Browser Window" context menu item is also disabled after enabling/disabling multi-line tabs.
Thank you! I just fixed the first item. However changing the tabs behavior influences the Internal browser somehow and it closes all its windows. I don`t know how to fix that.
