Multiple Page Not Found Errors

I have installed Root Candy on several sites before and not had this problem. Recently I have installed it on two sites as the administrative theme and the site is throwing dozens of errors each time administrative functions are accessed.

The errors are all related to the fact that drupal appears to believe that png images are located in sites/all/misc/ when they are actually in \misc (just off root directory). Typical errors in dblog are:

http://domain-name/sites/all/misc/menu-expanded.png
http://domain-name/sites/all/misc/menu-collapsed.png
http://domain-name/sites/all/misc/menu-leaf.png

There are these and several more each time an admin function is selected - the referrer is always http://domain-name/admin/[function selected]

I am certain that Root Candy is somehow involved in this because if the Administrative theme is switched to something like Garland, the errors no longer occur.

Any advice you could give me would be much appreciated.
