Somehow I've managed to disable ctrl+home & ctrl-end key settings in one of my workspaces so they no longer go to the first/last line of the program file. I've gone into the "keys" screen and set them back to the Progress defaults to no effect.
I'm thinking there's a setting somewhere in PDS which controls that controls this and that I'm missing - has anyone else run into this and have a fix?
now its working...all hail the power of communities! :)
