This is not a programming question but I hope Microsoft programmer can see this and answer this easier.
All fine until I had a third monitor which is USB 3.0 to HDMI to DIV. Not able to adjust the gama, so performed A LOT OF changes to try to achieve the goal, but only found that whenever I click a window and hold (drag or not doesn’t matter), the window with its content both change to translucent (I would say 90% transparent, barely see content, but see clearly the under window). Now Outlook and some old software (written in VC++6.0 by our team member) doesn’t do this but most windows in Win 7 and new software (IE, skype, SAP, ) does this and this annoyes me. I want non-transparent window when I drag it. can anyone help? Thanks.
A Microsoft expert answered that this was caused by nVidia setting. When nVidia manager is used, all windows become translucent when clicked and held by default.
