Thanks for pointing this problem to me Peter. I have never encountered
this
error before.
What version of Dolphin are you using?

I am using Dolphin 6, but not the latest version - it displays as 6.0 PL1.
But I suspect the reason I see the problem and you don't is to do with the
size of the GraphView window in the demo. If it is related to the size of
the screen, it could easily be that txtExtent x will give an odd number on
one machine and an even number on another.

Yes it already is a toggle, and yes I wanted to show 'with something like
check marks' on the context menu items if they were enabled or not. But I
never could figure out a way to do it. If you can figure it how to do so,
then please do and post the solution here.

In my existing app (developed in Dolphin 5.1.4 and not yet migrated) I can
show check marks on active toggles, but I can't remember exactly how I did
it. I shall look at it again. An alternative would be to change the wording
of the menu item - e.g. put 'hide cross hairs' if they are on view.

A lot of GraphView was just 'kludged' together in order to get it working
quickly. I'm sure that it cold be streamlined quite a bit and made much
more
efficient. Please feel free to play with it and improve it. Also, please
post any improvements here.

Will do.

Thanks again

Peter
