I have a strange problem here - maybe somebody has experience in this area and might think of a solution.
We have build a straightforward GUI. It consists of several screens, which can be swiped (gestures on a touchpanel) left and right. On some screens we use dialogs, which pop up to ask for some input.
For documentation purposes we have also programmed some screenshot functionality, so: if somebody gives the commadn !screenshot over the usb-serial, a handler will fetch the pixel-data and send it over the serial line where the receiver saves it as bitmap to disk.
What we see here is, that for every screen this code works perfect. But if we show dialogs, the code crashes immediately.
Does anybody know, what might go wrong here?
TIA
Marc
