text: problem with laptop keyboard--certain keys not working? well, two days ago, my "r" key would type several (1-4) "r"'s at a time, which was mildly annoying, but also somewhat amusing. i did not notice problems with other keys.  since yesterday, however, the "r" key hasn't worked; neither has the 4 in the number line, nor the f4 key.  i am using a fairly new (<2 years) ibook.  i can't think of anything that precipitated the multiple "r"'s, nor can i think of anything that would've changed the multiple "r" problem into my current one. i've tried rebooting, and that was no help. does anyone know what could cause these problems? i suspect the r key is stuck or broken with contact made. you can try moving it up and down repeatedly to see if you can free it up. i would think you probably will need to replace the keyboard very soon anyway. if cost is a factor get one of the roll up keyboards and plug it into the external keyboard connector.
