Rocketdock icons?

[Devrij]

Having decided to get rid of a set in favour of a new one, I've discovered that the stack docklets' icons don't stick after a reboot. Some are the old icon set, and some revert to the stock setting of just a transparent square. Can anyone advise me as to how I might fix this? Thanks

EDIT: Just discovered one docklet disappeared, and another lost all the settings I had applied to it (ie no folder attached). wtf?

They never used to though, even with the old set of icons I installed. It's only since trying to change the icons a second time that it's started doing this. I'll give that a shot though and will report back.
