Firstly, thanks for a really useful product. It's saved my bacon many times!!
On pages like:
I've noticed when using the browse backup pages in the FireFox web browser (v1.5 and v2.0RC3) that when you click on a directory link (in the right-hand table) the position of the left-hand table moves to the left. Sometimes the position changes so much that the link you clicked on isn't under your mouse anymore, and so you have to click on the link again to change to that directory.
Edit the en.pm file in backuppc/lib/BackupPC/Lang
and search for the line that reads:
<tr><td valign="top">
Change this to:
<tr><td valign="top" width="150px">
(en.pm is for english - the other files also need updating for other translations to work too)
(You may need to use a different width - as I have tweaked my CSS file so that I am using smaller fonts. I will upload this file shortly too.)
Hope this helps
