TDS GTNXi seems to cause stuttering in Flysimware 414

[rickw844]

I just purchased the TDS GTNXi and am using it in the Flysimware 414. I've noticed stuttering every 5 seconds or so while in the 414 - whether on the ground or in the air.  I do not have this stuttering using the default Gns530 or the freeware version of the GTN750.  Is there a configuration option that I need to enable ( ore disable) to stop this annoying stuttering?

Thanks.
