I'm running AC8.1 & PM 3.1 on a mac under OS10.3.3 and when i open my lbk plotmaker keeps asking me to choose a server to mount although they are already mounted and i can only hit cancel (sometimes 20 or more times as it checks for the latest layouts). The file does open okay but when trying to add layouts importing viewset layouts from a plp file BG AC stalls with the same request to mount a server and I'm unable to add drawings to the layout book. A new & reset seems to fix temporarily and I've re-built permissions without any improvement. The server is windows 2000server SP2 but the problems started with the updates to 10.3.3. and AC R2. V2
