Have a look at the attached program. I can't understand why a clearing of 'Children' is not completed with one click of the 'Clear' button. Any ideas appreciated.

Do you want to destroy every PictureBox ?

Hi voutt, yes that is the idea. I have discovered that if I use gtk or gtk3 this does not work but try qt4 and it works!

Sometimes Gambas has problems with GTK..... :?

 I've put in a bug report so we will see what happens…
