[kde-linux] Locking widgets doesn't work correctly

[Abos Undso]

Hi,
I have KDE 4.2 installed. I personalized the bottom panel (task bar) 
according to my needs with the icons and spaces I require. Once happy 
with the looks, I locked the widgets. However, every time I restart the 
computer, the icons are displaced and the spacers have a different size :-(
Why aren't the widgets really locked when I lock them? Is there a way to 
avoid them being jumbled up?
Thanks, Connie
