I've tried changing the priority
Hi Svenl,
Are you talking about panels' priority or the priority of the layers ? (in that case, that would be the "intersection group number")
Basically, if two layers have different intersection group numbers, the objects placed on them won't interact with each other. Please see the following thread for a screenshot

Hope that helps.
