object creating bug/focus controls

I am having a heck of a problem with the controls since the newest patch. I always use the alt and ctrl with the arrow keys to zoom in and work on objects. Lately weird things are happening, like not being able to focus or ZOOM focusing way in suddenly. The biggest problem is when hitting alt the camera moves around the object I am trying to edit. Of course this makes creating objects very very difficult. I have been crashing a lot in the past day or two. Sometimes if I hit the esc key it seems to help in a temp manner. Also dont know if its related or not but the controls for just flying or walking seem to also be a bit messed up sometimes I am looking way up or way down for no apparent reason. (no didn't touch the arrow keys)

Well I hope this explains the situation well enough. I got orders backing up yikes.
