Thank you so much Jacqueline
This indeed works. But if something is done in the background then the
problem starts. (I am using the same version of LiveCode.)
I tried this:
on arrowKey theKey
put 1 into increment
put me into current_value
if theKey is "up" then
put current_value + increment into the target
repeat with i = 1 to 1000000
put 1+i into temp
end repeat
end if -- up
if theKey is "down" then
put current_value - increment into the target
end if -- down
pass arrowKey
end arrowKey
The down arrow works but up arrow has the problem I have mentioned.
