Needing help with one problem about form focusing.

Hello everyone,

I am developing an application that basically mimics RM Tutor, but a remote version over a network (I suggest you Google RM Tutor so you get my context).

The part that I'm having trouble with is the part where you can view client screens.
I posted something like this on DreamInCode and some nasty people flagged it as spyware;
I assure you this is just copying something legal. The reason I need to make my own version is because I am placing in some of my own functions.

So, now for the problem.

When the client application (sending screenshots) goes out of focus, no longer are screenshots sent. This is very frustrating as it holds up the whole project, which has Teacher-Student messaging capabilities.

Could anyone please suggest a reason as to why the client application does not send when not in focus?
It should constantly send screenshots regardless of the focused application.

Thanks very much and please don't flag as spyware as it isn't! :)
