This question is a bit too general to answer.
How do you send your messsages from A to B, and how do you catch them

I'm guessing you have a SendMessage (or PostMessage?) in your code somewhere.
Perhaps the Handle is not the one you expect?
For example if you determine it by a FindWindow with form.Caption and you run as administrator you will not find it.
And what if you have multiple captions with text and you try to find it? You only do a SendMessage to the first found.
So therefor, what mechanism do you use and are you 100% sure of that outgoing messages work?
