Full screen windows 7 taskbar bug
Since the recent install of Flash Player 11 (v11,1,102,55) there was irritating problem on the laptop of my wife. When YouTube flash video were put in full screen the Windows 7 taskbar would remain visible.
The laptop screen is 1920 x 1200 so standard the DPI setting of the display is put to 150. If I would put the DPI to the standard setting the taskbar will disappear with full screen video but then everything is too small in windows. At first I did not release it could a problem with the Flash Player but when I did come to that conclusion I had to apply the following to the plugin-container program which is situated in the webbrowser install folder. In this case Mozilla Firefox.
After selecting the properties of plugin-container I went to the compatibility tab and put a flag in the option "Disable display scaling on high DPI settings". This basically solved the annoying problem but frankly such a sloppy fault in a commonly used program like Flash Player should not be there. I advise Adobe to correct this in the next version. There are quite a lot people these days who have laptops with HD resolution so fix it!
In the mean time I hope this will be of help to people who have a similar problem.
