The script runs fine but then the cursor freezes in

cursor is locked in the same place in all open apps, so switching
between finder etc. and LC doesn't help. Using shortcuts to switch
in and out of browse/edit mode doesn't work. The only way out I have
found in the dev environment is to invoke the preferences stack via
shortcut, and THEN switch between browse and edit mode via keyboard.
This allows the cursor to move, but it sticks with whatever icon was
set until it feels like changing for no obvious reason, although
sometimes in response to a command. I have tried various cursor
related commands within the "finish" handler, all of which appear to
be executed correctly, but always followed by the system wide cursor
lock up.
Running the debugger prevents the problem arising, so it isn't much
help. Sadly, the problem isn't restricted to the dev environment,
and I have to force quit standalones on Mac. All this is on Mac,
running LC 4.0 and 4.5 Could it be a problem with the mac cursor
stack? If so, how should I set about exploring that possibility?
As a guess, it sounds like you have a script running that isn't yielding
time to the engine. Cursors don't update until all pending handlers have
finished. If you have something going forever in the background, there
won't be any idle time in which the engine can do cleanup.
You could try adding a "wait 1 with messages" here and there to see if
that fixes it. A better approach would be to find out what's preventing
the engine from getting any idle time.
Specifically setting the cursor should have worked though, so I'm not
sure what could be going on. I'm just jumping in because no one else did.
