Openoffice and shared network drives

It was maybe discussed, but I did not found anything. I am using opensuse 11.0 with kde 4.2. Today I have updated openoffice from version 3.1.0 to 3.1.1. In previous version I can open and save any files from network shared drives, but now it doesnt work. Shared files are on a computer with Win XP.
Does anybody know what I can do? It is not comfortable to copy files, change them and then copy back to shared folder.
Thank you for any hints
