I set some Construction Layers, the dotted lines. But this solid lines appear without my action, if i remove this lines my boxes disappear too...?!

Sorry now i find the reason. It was the button with the printer symbol.

Hi fritz,

the misleading Printer icon was replaced in later versions, please upgrade your LC
