On a simple window I have 2 buttons, and on text widget to display time, and is updated in GUI thread.
Click on one button opens a MESSAGEBOX with a small OK button.
I have 2 problems:
When the box is opened it seem like it is blocking the thread, and the text widget time is not undated

This is the same with PC simulation and the real system.

Whoever, button click works fine on PC, but not on the real system, as soon as the button is pressed, it changes color to its pressed state, and wait, when I touch the button again, the messegbox opens.
What am I doing wrong? This works ok on the PC simulation, so I assume it has to do with my OS, ( only single GUI task is running)

When I open my own dialog box, the main window does not freeze.
Why the library massegebox dialog stops the background window update??
