HyperCard: Behavior of Click Command (7/92)

There might be a circumstance when HyperCard users set the lockscreen to
true, scroll a field, and then click at a location that they think will be
a line not currently visible.

This does not work. Next they might try and do the same thing without the
lockscreen set to true, and it does work. What's going on?

The click command works only on a REAL screen location rather than an
intended one.

In the situation given, HyperCard does store the scroll of the screen in an
internal data structure, but it is not available with the click command
because it can't access internal data structures -- only the actual screen
location. Therefore, try unlocking the screen before clicking at the new
location.
