Hi,
the following Bug created a crash in v9, corrupted lightshow attached. To reproduce error do the following steps: add at least two devices of the same type, in my case two moving heads found in the library.
Re open the edit window for device 1, open channel pan, set "head number" to e.g. 1. Close window. Re open the edit window for device 2, open channel pan, set "head number" to e.g. 2. Software crashes, show is corrupted, no entry in error log.
