i think it's all keyboard battery problems. for what it's worth, the cheap regular batteries on my keyboard died a little while ago and got a full-blown attack of beeps and spontaneous typing earlier tonight. i put those cheapie batteries in last week to replace the alkaline batteries that originally came with the keyboard. when the previous alkaline batteries died and went to battery heaven, they also went in a full blaze of glory with an all-out attack of beeping and spontaneous typing.
it seems like the keyboard really uses up batteries and when they are about to go, then i would get that weird beeping and spontaneous typing. it was like regular typing and also using the ctrl and alt keys. i had to shut off the webplayer to stop the beeping. i would try turning on the webplayer again only to get the weird beeping and the spontaneous typing again. what i then did was use my hand to cover the sensor thingie on front of the keyboard and then the beeping/typing would stop. remove my hand from the sensor and the beeping/typing starts up again. cover, uncover, cover, uncover. then i pulled plug on the webplayer again when i had enough of that nonsense. i took a couple alkaline batteries out of a TV remote control and put the batteries in the keyboard. i put the cheapie batteries in the remote control and tried to turn on the TV, but since the batteries were "dead", well, surprise, surprise, the TV would not turn on. then turn on the webplayer and point the keyboard with the alkaline batteries loaded, and the webplayer works a-okay since i'm posting this message.
yesterday and earlier today what i notieced prior to this attack of the weird beeping/typing, i noticed a weird beep once in a while that was not caused by any errors. what i'm guessing is that those unexplained single beeps mean that the keyboard batteries were about to bite the big one and if i did not change the batteries then i would get the big attack of the beeps and spontaneous typing. it's as if the batteries want to go out in one big bang with an all-out paralyzing attack of beeping and spontaneous typing if you don't change the batteries after being warned by the single beeps.
also, i noticed before the big attack was that the mouse was a little slower to respond than usual. so if you the mouse is slow to respond and if you get those single "unexplained" beeps, then change the batteries or get hit with the big one.
