Error 1024: An error occurred while attempting to retrieve a folder.

I've read some posts on this error, but I cannot seem to find a resolution.  Has anyone seen this error in Vault:

Error 1024: An error occurred while attempting to retrieve a folder.

It happens every time I do a copy design.  In the copy design window, if I simply hover my mouse cursor over a part located in Content Center, this message pops up repeatedly.  Not only is this annoying, but it also makes it impossible to change any of these parts from "reuse" to "copy".

I've been trying to ignore or work around this for about a year, as this behavior did not start until we upgraded to 2011.

Any help on this would be greatly appreciated.

I have discovered that if you change the folder structure in the vault and in the Project, the project must be checked back in before the vault recognises the folder structure change. 

Checking in the project file worked for me
