correction: this is in Navigation mode, not just crosshairs

one more thing: to change navigator location after zoom, you need to hover to the "true" location of navigator (same as before zoom) to grab and move the widget

I do not understand the issue.

The crosshairs should stay at the same RAS position. If one window is zoomed, the crosshair in that window should still map the same RAS.

Is this not happening?

Is it a refresh problem? I.e. the crosshair looks to be at the wrong spot but if you move mouse into the window, it jumps to the right place.

Jim, to reproduce:

1) load MR head
2) turn on small basic crosshair
3) turn on navigation
4) zoom in and out a slice with navigator visible

What I see is that XY of the crosshair stays at the same position. It is not a refresh problem, because it does not reset after I change slice or move mouse.

I experienced the same issue: if you are in navigation mode and you zoom you cannot continue the navigation since the current position of the cursor is not refreshed in the slice view.

Since I really need this problem to be fixed, would there be a way to intecept the end of pan/zoom events so that I can update the crosshair position accordingly? Thanks a lot

Fixed in r22200.

Added OnSliceNodeModifiedEvent() to update the Crosshair display position when the SliceNode is modified.
