VIDEO WINDOW screen problem

[digitalshark]

Hello there. Can someone please help me...I am really baffled as to why I can't enlarge any video screens anymore for the past 2 days. In youtube I use to be able to enlarge the screen by pressing the lower right hand button they provide. Also, I can't even enlarge any streaming video windows either. I have fire walls and anti virus that I have disabled and still doesn't work. I really appreciate if anyone can help...I am a rookie when it comes to troubleshooting pc's. I don't know if I have to readjust something with my pc or something.

thanks

this sounds rather odd...

to properly diagnose your problem, we will need to know some of your system specs.

initial thoughts: its possible your adobe flash player is out of date; you can always try going to adobe and downloading a newer version of that but i rather doubt its the problem. I doubt that your firewall or AV is causing this problem also so please disable them only as a last resort.

Do you get an error message when you try to use full screen for your players? what other programs are effected by this? If all the effected media is being streamed through your web browser, which type are you using (mozilla firefox, internet explorer, etc)? have you found you have the same problem when using a program like windows media player or quicktime?
