youtube videos audio/video recently became sorely out of sync and switching from html5 to flash solved the problem but caused youtube playback control (bottom bar and top left and right corners) to become too tiny to see. (yes i read on here adobe flash is aware and working on the problem and i signed up for solution notifications. i just reposted this question in case anyone else has a new solution). its not my resolution. apps (enlarge font, zoom) did not work. also since changing to flash, youtube videos are freezing up a lot. like when i go full screen, video often turns black and freezes. also another problem that recently started with both html5 and flash is zooming into youtube comments above 170% causes the comment field to disappear and page wont zoom out. i had recently changed from win xp to win 7 pro, is this the cause somehow? i need to make youtube comments; thats 90% of the fun! i watch youtube on desktop monitor from 10' away with wireless keyboard and mouse and need to zoom in far to type comments and was able to since 2014 until 2 months ago.
