Hi.  I hope someone here can help.  This afternoon, my carpel tunnel was feeling good enough that I decided to start work on a new model.  I opened C7 Pro as usual, however, something weird is happening.  When I try to use the XZ Track Tool to move the camera up, down, in, or out, It barely moves.  It's the same with all of the cameras.  It's like the camera is running into an invisible wall.  I tried resetting all the preferences to default, but that didn't help.  All Constraints are turned off.  This is in a brand new blank document.  The only thing I can think of was that I did install the closed Beta of C8, but there have been no changes to C7.  I really don't want to have to go through reinstalling it if I can avoid it.  Thanks in advance for any help.
