Penryn Macbook Pro which I've owned for 3 months now. Been having a very strange problem the past week or so. This only occurs after I've been using the MBP for a few hours. Basically a few things occur: 1. The trackpad will not respond to my touch gestures. Nor will the scroll bar. 2. Clicking the search icon in the upper right hand corner after i've entered a word in firefox results in no action. 3. Attempting to visit a bookmark results in no action or....... 4. If it does bring the webpage up, pictures are missing entirely, or the site itself just looks like a huge mess with text jumbled together. Restarting the computer fixes the problem for an hour or so, and then it reverts to the same issues again, unless I shut it down and use it the following day. I've also noticed a lag in visiting websites the past few weeks. What was once an immediate upload on my N network can at times be a brief pause highlighted by a circular ball spinning for a few seconds. Does anyone have any idea as to what my problem is? It really is driving me crazy. Aside from this issue, I love my MBP. But I switched from PC's expecting a smooth experience, and I hate to say it but things like this never happened with my dumpy Dell Inspirion laptop. Let me know what you think. Thanks.
