ES Commanche Heading Bug

Hi,After updating my monitor to a wide screen, I re-installed the Twin Comanche to take advantage of the fix for hotspots in the 2d (widescreen) panel. The install was successful; however, the Bendix King KI 825 seems to now be missing the heading bug. The heading bug is there in the ARC Map mode, but not in the HSI or 360 Map modes. The numeric heading readout is present in all modes and seems to function normally, it's just the 2 bar bug that is missing. I'm using the FSX version.The problem occurs with all textures, and both 2d and vc panels. I haven't found anyone else having this problem on the forums. Has anyone else seen this problem and is there anything you can suggest?Dale
