...application not responding... wait or Force Quit ( QT )

[Anonymous_Banned275]

Ever since I started using QProcess ( and with Ubuntu 21,10 ) I keep getting these " MDI Example not responding" error during run time. . My app name is "MDI " and the QProcess takes roughly 30 seconds to complete.
Sometime I get two or three of same messages BEFORE the QProcess complete.

To be honest - I have seen SAME message during other - standard _ Ubuntu applications. So I cannot really blame QT only. 

Any suggestion how to find out what is causing this ?

Are you blocking the UI event loop? The QProcess should be left to run in the background and your code should just react to signals.
