LC Bug: No Mouse Wheel Scroll after a Ctrl-Click Launch

[Curry Kenworthy]

LC Bug:

After you Ctrl-click a link that uses "launch"
the text field will NOT scroll with the Mouse Wheel
unless you first press a keyboard key or modifier.

Not only is Ctrl-click the official way
to activate links while editing text in LiveCode,
but MS Word uses Ctrl-click for links too,
so it's a widely-trained habit! :)

Here's the bug report:

More details:

This bug does not specifically require Ctrl or click.
(Or even an edited field.) Any launch or shell
while a modifier key is down will trigger it.

Then LC fields aren't aware of modifier key status.
The test stack demos two ways to trigger this.

Bonus side effect:

This might be a valuable clue to explain
some rare LC Script Editor glitches, too!
(Each fix gets us closer to a rock-solid SE.)

Platform:

Tested with LC 9.6.6-rc-2 on Windows 10.
My current recipe did NOT trigger for me on Mac.
So, I'm not sure yet whether Mac is affected
by this bug or anything similar.

That wraps up my Weekend Big-Game LC Bug Hunt!
