We have over 300 users of a special land surveying software LANDESIGN 1.17 made for Classic OS9 and we were able to run it successfully with the modified Sheepshaver 2.3 "Classic On Intel 4.01" installed on OSX 10.5.1 on an MB Pro Intel but after updating to OSX 10.5.4, this Classic application it is not working properly in COI 4.01 The OS9 loads ok but when I tried to open the Landesign application from within OS9, a dialog windows display "the application could noy be opened because the application that was used to create could not be found" It was running great before. Is there any other OS9 application that runs in OSX 10.5.4 on an Intel Mac? HELP PLEASE!
