O.T. Missing Folder/files

Why would I change partitions on the 780 and the 8500?
I don't understand the purpose behind it?

The C: partition is where all of my work is; in My Documents.
Why would I keep backups on a D: partition? I'm not understanding
the reasoning behind this. Isn't the whole purpose of external hd's is
for Mrimg backups?

The bookmark toolbar/bookmark menu still does not show as it normally
does.

We can't move forward until we resolve this. Should I Import bookmarks
or click Getting Started?

We already did the Helper.exe for Sea Monkey on the 780 because it wasn't
in Programs and Features and I lost the bookmarks right afterwards.

On the 8500 I just need to click the new version but in both cases they did
not install correctly and we'll have to see whether they revert to the old version
or install the new version. Correct?
However because Sea Monkey threw up a loop by not installing correctly before
I do anything on the 8500 I want to clone it. I'm not taking any chances.

So let's concentrate on bringing the bookmark menu back on the 780 which we
should be able to do if not the backspace key. Then we can move from there.

What do you think?
