Hi,
I just installed Laz 1.8.4 on Manjaro (arch based) with KDE Plasma.
installed with the GTK2 IDE widgets and works fine except I can't double click on any controls to create/go to the even.
For example if I drop a button and double click on it, it does nothing, no error just nothing.
I do have the IDE using the docked interface, I will try it without the anchor docking package installed and see if it's related to that.
