Create a sub-folder 'sub1' under workroom 'test1'.
Double-click on sub-folder, and path shows '/test1/sub1', which is correct. Go back up to 'test1', and repeat.
This time the path shows '/sub1'.
We have encountered this issue as well, which is a nuisance when the Editors are looking for the value to populate "Path in the file system" (Property: WebBaseURL) for file listings.
In this respect, it'd be nice with a feature whereby the Editors uses the Link Tool for selecting directories (and not only files).
