Uuups, you touched a critical area ;-)

I am sorry, but not all Region methods are "VNC-aware", meaning, that a
resulting Region, might "not know", that it is on a VNC screen.

... and I had a look into this group of methods for rastering a region:
you might find bugs (result not as expected) besides the mentioned not-
VNC-aware problem.

so
vnc.getRow(3, 4).getCol(1, 3)
might be calculated correctly, but is not flagged as being on the vnc-screen

What you can do:

make a method:
public Region asVNC(Region reg, IScreen vnc) {
    reg.setOtherScreen(vnc);
    return reg

and use it:
asVNC(vnc.getRow(3, 4).getCol(1, 3), vnc).click(); 

ugly, but works.

if the function asVNC is in the same class file as your code:
public Region asVNC(Region reg) {
    reg.setOtherScreen(vnc);
    return reg

and
asVNC(vnc.getRow(3, 4).getCol(1, 3)).click();

less ugly, but now depends on the global variable vnc.

I am sorry, but I doubt, that I get to that problem before beginning of
next year.

So you have to live with it for now.
