Unable to drag container control on to window in IDE

Hi all, copied some (working) container controls from an existing project in to another one. For some reason, I can’t drag those containers from the Library in the IDE on to a window in the IDE. I get the drag rect, but on mouse up, nothing happens… is this an IDE issue / bug? For info, project compiles OK, no errors.

Anyone else had this?


With more information (Xojo version, OS version, Control Name), we may be able to help you.

Humble apols… 2022 r1.1, Mojave, ContainerControl…

Forgot to to change superclass from ContainerControl to DesktopContainer. D’oh!
