I have a number of design models that I have been working with over the last few weeks, and I have noticed that there seems to be a consistent odd behavior for the zoom function, which has been a mainstay for me via the scroll wheel. I had not noticed this until recently, within the last couple of weeks or so.
Immediately after opening a model, the scroll wheel is dead regarding the zoom functionality, if this is the first thing tried (which is often the case for me). The zoom function does work by selection of the plus/minus mouse-drag action, so this isn't a huge issue. At some point soon after doing some other tasks, the scroll wheel is functional again for zoom use. I haven't analyzed this behavior for conditional detail regarding the resumption of scroll wheel usability yet, but I wanted to find out if anyone else notices this same issue, or if I'm the ONLY one;-)
