Looking for suggestions here.  Lately (at least the last few releases) Cross Track Error in my Expedition display is incorrect or simply missing.

When XTE is small (e.g. .2nm) XTE seems to round down to zero.  When it is large (e.g. 1.5nm) XTE is very small.

My routes are created only on Expedition.  There is a previous and next mark, and I have a solid GPS position.

Network includes B&G H2000, Vesper Cortex, Zeus3.

Any suggestions of what to look for would be appreciated.  

Thanks!

PS.  I have screen shots but can't figure out how to include them.
