Black Screen on Flight Radar

[por930]

Hi Mike,
Thank you for your reply. I did a few searches, but had too many words in the search string (e.g black screen)....When I looked at the recommendations about IE, Chrome etc, I changed my search engine to Chrome and the problem was solved. I was provided with the handle to change the screen contrast.
I notice distinct holes in the coverage and only some aircraft seem to have the ability to send signals and maybe a lack of receivers to provide coverage in the net work. I see non in the USA at all. Fantastic site though.

I made a search on "black" on the forum and found this:

Hi,
My first time I have used Flight Radar and inadvertanly I moved the top right bar to darken the screen. I can't adjust the bar back again and now have a black screen. How do I "grab" the handle of the adjustment bar?
Regards
Geoff
