Custom Appearances folder

I'm having an issue with my custom Appearances folder (SW2008SP1.1).
I can add a custom folder as a file location formaterials/appearances in PhotoWorks, but after a reboot it is gonefrom the task pane and I have to browse for it manually every time,very irritating.

In the previous versions of SW I simply put all my custom folders(material, scene, light) in the .../data/PhotoWorks/custom folderand all worked well, but that folder doesn't exist anymore inSW2008.

Now I found out that the material files are saved in the...\data\graphics\materials folder, but if I add a new customfolder in there it doesn't show up either in the task pane.

Does anyone know how to fix this problem?SolidworksPhotoworks
