I have recently upgraded my machine to Windows 7 from XP, we are running on a network and using version 8.1B(the latest). all the other machines on the network are running xp still. I was setting up the new workstation and of course the columns in Purchase order are not the same so i went to edit them. I am unable to add or show columns. When I go to remove one ie. Unit of measure it removes the wrong column and when i go to show it again it will not allow me to put them back in. Now i am left with price and thats it...has anyone come across this problem before? I have full rights to edit in both user profile and on the PC itself. if I go back to my old machine it works just fine. I have tried to change the compatability under properties on the server to windows 2000 ( the newest version avail) however on the workstations in still shows compatability version windows 95.
