The problem appears to be in the "Lighten" paint effect -- when you call it
by script or choose it from the Paint menu (the power key seems to be
unaffected...) -- in combination with the "doMenu" handler in the Power
Tools stack.
This problem also effects several of the demo scripts in the HyperTalk
Reference Stack (those that call doMenu "Revert"). Most of these demos
involve painting tools/ paint properties and failure to revert leaves
paint on the card.
The following will fail with the Power Tools stack in use: Create a card
that's filled with black paint -- and execute the following from a handler
choose select tool
doMenu "Select All" -- or make any non-empty selection
doMenu "Lighten" -- this works!
doMenu "Lighten" -- nothing happens
Any other affected commands will fail if added to the end of this script.
The selection seems to be getting lost after the first command.
Workarounds for other scripters (none is very effective):
* Make sure Power Tools is not in use.
* Re-select an area before calling subsequent commands in the Paint menu.
