Ideas preventing 'spillover' from ControlSend?

[Gar]

Here's the problem: I have a difficult to work with program that functions normally when ControlSend is used on it 9 out of 10 times. For example, if I send the 'up' key, it registers 'up' being pressed most of the time. However, at random, sometimes it registers 'up' being pressed twice - and I can't figure out why! I've put SendKeyDownDelay to 1 and even 0 and it still happens sometimes. There are large sleeps in between the ControlSends, so i know it's not doing ControlSend twice. Also, this random problem happens regardless of the keys sent. Anyone have any idea how I can prevent this?

Try these, they seem to work perfectly for me

Opt("SendKeyDownDelay", 100)
Opt("SendKeyDelay", 200)

Those settings make it double-up every time for me :/

Are you sure it is not your keyboard or anything? When I hook up a USB keyboard to my laptop it sometimes doesn't detect my up keypress, resulting in a long line of the same characters.

Try it on another computer.

What is the app? If we can't reproduce the error, we can't help.
