I have a Mac Book pro with a DELL 2408WFP. I have recently upgraded my Panone Huey to Huey Pro, in order to calibrate both monitors. I have followed all the steps in order to calibrate main monitor (the dell) but at the end, when the program ask me to move the application window in the second monitor to calibrate it anything append. I can only quit the application or Hit back... but in this case the frame appear again in main monitor. Anyone with Huey-pro, huey pro upgrade have experienced this problem? What should do append when you have moved huei application in second monitor? I have wrote to Pantone support one week ago, but still no answer. Thanks again to anyone who could help me.
