Hello Igor, I have done the necessary steps as suggested but no change. However, I have ended up checking the Display parameters and found out to be set at 16-bit rather of 32-bit. The problem has resolved itself when changing from 16 bit to true color 32 bit. So everything is OK now. I must have changed accidentally the parameters during installation of all the software on my new PC to end up with the issue. Thanks Lin and Igor for your time to help me with the issue and keep up the good work Igor with the upgrades. Denis
