I have a client that utilises WSS 3.0 on SBS 2008 quite heavily. They often use "My Network Places" to save documents to Share Point Libraries.
One machine (Running XP) cannot save to My Network Places (File > Save As)
using Adobe Reader X. All other applications (Word, Excel etc) are fine. All other XP clients on the network are fine...
When they browse to the WebDAV (My Network Places) folder, the sub folders do not appear (see screenshot)
