Pointer tool not working

[JonathanC at ag.nsw.gov.au]

I recently created a stack ("Launcher.rev") to act like HyperCard's Home 
stack. It works OK, but just then, when I went to edit a button, I 
discovered that the pointer tool wasn't working. When I choose the pointer 
tool (either from the palette or the Tools menu) and click on the button, 
instead of selecting it, it CLICKS it (as though the browse tool is 
active).

This only happens with this one stack (so far). I can still select objects 
by choosing "Card [or Stack] Inspector" from the Object menu and then 
finding the object I want from the Selection pop-up menu, or by using the 
Application Browser, but why can't I select them directly?
