problems configuring kicker

hi, everybody . . .

i've encountered a weirdness as i try to arrange some icons on my kicker. i can right click and move them, but kicker behaves as if a new icon is being added instead of an old one being moved. the old one moves well enough, but everything on the right -- task list, spelling applet, calendar, gets squashed farther to the right. so i have blank space in the icon section and the applets and such are all squashed together.

so, is there a configuration option that lets me drag everything back to where it should be?

thanks very much.
