Comment 3 for bug 115761

Korsaire,
I have attempted this on my system, both with, and without desktop effects enabled.

Steps I took:
* (Desktop effects initially enabled)
* Right click on top panel bar
* Select properties
* Set orientation to left
* Logout
* Login
* Observe bar still on left.
* Set bar to top, log out and in.
* Observer still on top
* Set bottom bar to left
* Log out
* Log in
* Observe bottom bar still on left
* Set bottom bar to bottom
* log out
* log in
* observe bottom bar still on bottom.
* Disable desktop effects
* Right click on top panel bar
* Select properties
* Set orientation to left
* Logout
* Login
* Observe bar still on left.
* Set bar to top, log out and in.
* Observer still on top
* Set bottom bar to left
* Log out
* Log in
* Observe bottom bar still on left
* Set bottom bar to bottom
* log out
* log in
* observe bottom bar still on bottom.

So I have not been able to reproduce this at all.

Is your Ubuntu a fresh 7.04 install, or an upgrade?

Did you carry over a profile (/home directory) from a previous installation?

Can you try (as a test step) creating a new user in Users and Groups, with no other additional settings or changes, log in as them, and then perform the steps I outline above. Please let me know the results.

Thanks
