I got a new Acer 11.6'' laptop for Cyber Monday sale and one of the first things I did when it got here was to install the Opera Browser. It's a really slick browser but I'm having two problems that I can't solve. The first is that the Zoom adjust on it's own out of no where. I want it to be on 110 but when I move the curser the screne can auto-zoom anywhere from 90 to 500. I can't find a way to lock the zoom. Does anyone know how to do this?

My other problem is less frequent but just as annoying. I like to pull down the slider on the right side. Sometimes when I start to pull it will openw a new window, then I have to close it and move the cursor to the arrow at the bottom and move the cursor down that way. What's going on with this? How to I get this thing working right?
