The only place they could select the pointer tool is in the IDE. I am almost
certain this is not possible in a standalone. Are the users co-developers?
I tried this out myself and can confirm this. I tried using copy then paste in
a handler I called in 0 seconds, but the copy clearly did not work because I
got a graphic I had copied earlier.
Here is what I did instead. Put this in your card script:
on deleteKey
if word 1 of the selectedObject contains "field" then
answer "You can't do that!" as sheet
exit to top
end if
pass deleteKey
end deleteKey
on backspaceKey
if word 1 of the selectedObject contains "field" then
answer "You can't do that!" as sheet
exit to top
end if
pass backspaceKey
end backspaceKey
Works like a charm.
