Not sure if this is the same, but it sounds similar to something I have experienced in recent squeaks. See if this helps at all:

Hi Eliot and all,
I have just noticed in Squeak 5.2 that attempting to scroll a text pane beyond its scroll limit causes the text cursor to start moving. So, for example, when I have a selected expression in the debugger, and I simply scroll the text pane, I hit the end and lose the selection, which is incredibly annoying.
Does anyone know why this is and how to fix it?
Thanks
