I have an Imac and previously my "scroll wheel" function on the mouse would expand and contract the chart but it no longer works.  The scroll function works everywhere else on the computer in other docs but just not in TC2000.  This started happening recently.  Has anyone else had this sort of issue before? I checked my mouse settings on the computer and everything checks out.  Just curious.

I don't know why it would have recently stopped working. The scroll wheel still zooms in and out for me, but I'm using a Windows computer. You may want to contact technical support.
