Unable to select or change icons/images for any button through command editor select icon dialog. When I click an icon from the list it will not select it (the dialog will flicker once), when I double click an icon it will insert no icon (or the blank one first in the list).
I tried resetting all settings by deleting everything within /dopusdata and also clearing the other folder /dopuslocaldata. After the reset the problem persists. I then downgraded to 12.0.11 and everything went back to normal. So it must be 12.0.12 related. I don't think this happened right away but after a bit it suddenly wouldn't let me select icons.
Renaming the file did not work. I just noticed I can select one icon, that would be the one that is set when the icon dialog is opened. I attached a video of the problem.
