Hello everybody

I have a problem with an application.
Its goal is to open a new dialog box every 3 minutes.
I created a thread with afxBeginThread, waiting three minutes with a waitable timer and then openning the dialog box.
But, when this thread finishes instanciating, creating and showing the dialog box, it quits. At this very moment, the dialog box also closes itself. (This works perfectly when clicking on a button on the main application.)
I saw some posts telling that it's not a good idea to use worker threads to manage UI, but I don't know how to do it in another way. Any idea???

Thanks in advance
