Adobe Flash Player Storage Request

I have this Adobe Flash Player Storage request where this little box comes up in the middle of youtube and won't go away. Gives the option to allow or deny. Press deny, it doesn't go away.

Secondly, not sure if problem is separate or relate to above, but my cursor jumps around when i'm typing text and the text will go into a sentence already written.

Please advise. Thanks.

PS. I did download Adobe Flash Player a time ago when my Windows media Player wasn't working. The Media Player started working again. Maybe I should uninstall this Adobe Flash Player??

First, try installing the latest version of Flash. Download here: http://get.adobe.com/flashplayer/

Your cursor jumping problem is different. You're using a laptop, correct? The pressure plate for the touchpad is sensitive to any weight on the keyboard, so if you rest your palms on the keyboard, the touchpad reacts and moves the cursor around. Some computers have software with the mouse settings to overcome this.

And, an installation of Windows that is slowing down can cause delays in typing, as the computer struggles to work and the keyboard waits in a queue. When the computer frees up time, the keyboard jumps into action... but for stuff you've already typed, which gets mixed up with stuff you are typing now.

thanks.
