I have 8 hours trying to figure this one out.
But it's solved.
If you alter any bookmarks in THE K-Meleon non
Sandboxed version, it changes the bookmarks in the
profile for the non Sandboxed version but not the
profile for the Sandboxed version.
Solution for me that worked.
Uninstall Sandboxie before altering any bookmarks.
Then alter the bookmarks and reinstall Sandboxie.
Uninstall/installing Sandboxie is very fast.
Hope this helps somebody. Maybe somebody else has
a better solution.

In addition to the previous message.
The uninstall doesn't take out all the goodies
of Sandbox. Go to Program Files and look for "Sandbox".
Delete everything in this folder.

If you don't delete the contents of a sandbox, Sandboxie does not re-import the relevant un-sandboxed files. Just delete the contents of the sandbox K-Meleon runs in, with the Sandboxie Control. Sandboxie will automatically import the revised bookmarks when you re-start K-Meleon.

Thanks for the reply.
I thought there had to be a better way.
I'm new to Sandboxie and my reading so far has
not divulged how to delete the Sandbox.
If you would be so kind as to be a little more
specific it would be appreciated.
JPS

1. right click the sandboxie icon
2. default box/delete contents
3. delete sandbox
