CAD stops wheel-zooming at drawings edges - HELP

[adamsnez]

Hi, this problem just started on a drawing in our department...

 

We use wheel zoom, and you can zoom out forever, but zooming in STOPS once the view area hits the outside of the drawing/outter lines in plan view, model space.

 

Uhhh, help?? NO CLUE what command this could be, how to check it, or whatnot.. Nothing got changed, as far as any one doing it consciously. THANKS!????!!

 

EDIT: REGEN/REGENALL doesnt work, as explained here;

I read that link to mean that REGEN is the solution

 

Solution

When the drawing is loaded, the display is cached in memory. When you perform the zoom out, the memory allotted is used up and the zoom action is stopped. If you use the REGEN command or zoom out using the View drop-down menu, the cache is recalculated and scroll zooming can continue.

The command line should be telling you something at that point when it stops. What does it say when that happens?
