app freezing/stalling when title bar is clicked

(1/2) > >>

dieselnutjob:
can someone tell me why an application stops if the title bar of the form is clicked and held clicked?

i have a simple multithreaded app, with a gui thread and a timer thread, and if a user clicks on the title bar, in order to move the app around on the desktop then even the background timer thread seems to stop (maybe it's when it calls an "updategui" event handler in the gui thread)

I have another more complex app which is trying to maintain a communication protocol in the background.  If I move the app on the desktop the protocol crashes because the app is not servicing packets when it should

i would like to be able to move an app whilst it still processed data inside

thanks

I tried compiling the app in Linux, and the problem goes away
so it's only a problem with Windows
anyone know how to stop it?

I found that the actual IDE suffers from the same problem.
If you click on the compile button, and then hold the mouse down on the title bar of the IDE, it stops compiling until you let go of the mouse.
Other windows programs don't that.
I think I will have to submit a bug report.

Does anyone found solution to this?
