MM crashes when closing a file

Hi,

I´m using MM 13.2.204 on Mac (Intel i7, masOC 11.3). Every time I close a file or the app. MM crashes (Message: MiondManager quits unexpectedly).

There is a error message in the report: "MindManager[3510:137766] *** WARNING: Method userSpaceScaleFactor in class NSView is deprecated on 10.7 and later. It should not be used in new applications. Use convertRectToBacking: instead."

is this a known error?

thanks for help

regards
