EV_MODEL_WORLD_CELL not updating

[Jimmy Johnson]

Okay, change of tack.  What I thought was a problem with pick-and-put, turns out to be a problem with windows not redrawing when expected.

My window contains an EV_MODEL_WORLD_CELL which holds many EV_MODELs in a scrollable area.  The window has zoom in/out buttons that scale the world of models.  The odd thing is that when clicking on the zoom button, the scroll bars react immediately as expected, but the contents of the window [i.e. the world & models] do not scale UNTIL AFTER the mouse is moved into the window.

Is there a way to make a window redraw [project?] without needing the mouse in the window?

Some more.  The window updates immediately when scaled down; but when scaled up the mouse must be moved over the window to see the result of scaling.
