Hi Raphael,

No worries Raphael. Thanks for all the suggestions, these I tried before submitting the thread. I had been desktop support, systems adminstrator and network administrator before, so have gone through all possible troubleshooting steps before submitting any problems to 2nd level. what I am not is a programmer and developer haha.

I had resolved it by atttaching external projector onto my laptop and moving back the window from the extended screen. Somehow it has something to do with the desktops being duplicated or extended when having dual displays.

Anyway, thanks for all the support.

Warmest regards
Lionel Loh
