Warp Ring Location previews are broken

Steps to recreate:

1. File->New
2. Quest->Misc Data->Warp Rings
3. Select '0' in "Warp Rings" window
4. Click 'Edit' button
5. Set 'Count' to 3 in "Ring 0 Warps" window
6. Select '1'
7. Observe warp location is screen 0x00 in mini-map on the "Ring 0 Warps" window
8. Click 'Edit' button
9. Click the square for screen 0x0F in matrix or type 0F into the "Screen: 0x" field
10. Click 'OK' button
11. Observe warp location is still screen 0x00 in mini-map on the "Ring 0 Warps" window, even though "Scr: 0x0F" is below it

The mini-map on the "Ring 0 Warp 1" is also affected.

The Warp Rings window is created by onWarpRings() in zquest.cpp

The actual window the preview is displayed on is created by EditWarpRing in zquest.cpp

When commenting out this line from the warpring_dlg array, the preview display disappears:

Code:
