When I use dual displays watching YouTube video, it can not switch to full screen mode correctly. I assume it is because YouTube flash client calculate width and height based on the total of dual displays, and render the video into one display. So it is only displayed in 1/4 size of one display (my two displays are of same resolution).
I have tested how videos from 163.com and sina.com are rendered in full screen mode with dual displays. I find both of them are fine. So it eliminates the possibility that bug is in Flash Player.
BTW, I did not find a way to stretch the video into two displays.
About a month ago, I found I could not print Analytics Dashboard from IE (my version is 7 already). Every time I tried to print Dashboard, the browser freezed. I have tried different computers and different printers. The symptom is the same.
Analytics Dashboard is the only report I can not print from IE, but other reports are fine.
I can print Analytics Dashboard from Firefox, but the print layout is not as well formatted as it is in IE. So I have to use IE to print this report.
After I realise Flash 10 is causing problem of uploading images in magento, I think it might be same Flash causing another problem. However, this time Flash 10 is fine, but Flash 9 is not. As my test result shows, Analytics Dashboard can be printed in IE with Flash 10 installed. I assume the symptom is affecting IE with Flash version lower than 10.
I do not like Flash, but between Flash 9 and Flash 10, I prefer the former for now. I think a good program should work both on Flash 9 and 10. So I reported this problem to Google for them to improve Analytics. It must be some recent changes that prevent Analytics Dashboard from being printed.
