Mail folders

Hi I've upgraded my own workstation from SuSE 7.3 to 8.0. Everything would seem to be fine apart from one very annoying problem.. After making a backup of my mail folders which are - Mail and mail folders - I find that when I start Kmail 1.4.1 with the old folders in place an error message appears on the screen which tells me that permissions are not set properly. This message then repeats itself for every mail folder. After a while the whole of KDE 3.0.1 locks up solid and I have to re-boot. Does anyone how to sort out this problem ? I've updated KDE from the SuSE site and the problem persists. Can't find any reference to this in the SuSE support site. Thanks -- Richard www.sheflug.co.uk
