Hi,
when I click the eyedropper tool to colour pick something in C4D I get this error message and a crash. (see img)
Every time.
OSX
C4D R19
Corona B2 RC3
Could you send us the bug report? We know you have one, it says it right there on the error message 
followed the file path but can’t find the location of report
Does this happen all the time or just randomly? We made a new release today if you haven’t heard, can you try installing it to see if the problem remains? Thanks
