Hi there, Hmmm not sure if this is in the right place but... I have a Macbook that has been running slow for the last 2 days. I scouted the net and ended up finding out I should check my Activity Monitor, which I did. There is a "WD Button Manager" that will flash up for a second and then disappear . It says that it is using 96% of my CPU. (Does this explain why my mac is slow? Even as I type this there is a delay for a second and then the words appear!) I think its for a Western Digital external HD I had a while back but I never use now. So i tried to find the program and did, I tried to drop it in the trash and delete it but it gives me the message, cant trash because it is open. But I cant open it when I click on the icon, it opens omnioutliner? (no idea what this program does!) Any ideas? I'm basically a computer novice, I only really write in word and surf the web. It is driving me nuts! I need to work! What should I do? Thanks in advance.
