Hi Solomon,
I experienced this problem once, ArcMap not refreshing the actual contents
of a just-modified feature class. I am not sure this is your problem, but
you may want to try the solution that worked for me.
I got the reference to the feature class by accesing it through the layer
(IFeatureLayer interface) instead of opening it from the Workspace. Then I
modified the Feature Class (& refreshed display) and everything went well,
so I guess you have to use the same feature class object ArcMap has already
created in order to make it work.
If this works, you'd better write some code to check if the user has already
loaded the GPS_MASTER layer, getting the reference from the Layer inside the
document if this is the case.
Hope this helps,
Santiago
