We are using SharePoint 2007 SP2 with RadEditor 5.8.
I added the DocumentsPaths property to customize the available document libraries.
This is my entry:
The first one should point to the Documents Lib on the CURRENT Subsite.
The second should point to the root of the site collection.
But both entries are pointing to the root of the site collection. With or without a leading "/".
The same setting works as intended with the ImagesPaths btw.
