Odd result from checking .SliceList.Count

Given that _thisRadio is a found and connected instance of Radio, I have found what seems to be an odd result from a test of the value of _thisRadio.SliceList.Count.

In this case, the radio is a 6300. If two slices are 'active', it is my assumption, that on connecting to said radio, SliceList.Count will be 2. Single stepping thru a simple program shows this to be the case until it gets to a line that says "If (_thisRadio.SliceList.Count > 1)", etc.

At this point, SliceList,Count becomes 0. If I set a variable to SliceList.Count, and test the variable there's no issue, but if I test directly, it will get changed to 0 every time.

I assume something is changing it, but there's nothing in place in the program that does so and I am unable to find anything in Flexlib that might be doing it (though searching thru it is a bit tedious when you aren't sure what you're looking for).
