I'm such an IDIOT! I guess I can cut-and-paste OK, but I'm not too swift at
reading the documentation. One of the other developers found the description
of the problem.

Here's a snippet of instruction from Randy's page:

Note: There's something weird going on with this code and Native code
compiling. Specifically, the app will crash if the return data type from
GetRemoteMACAddress is changed to String . try and modify this code to
return a string from the user reported a weird problem I have confirmed
with this particular code code when compiled to an exe using the Native code
option. The problem stems (for some reason) in the assignment of compiling
and the assignment of a string return type to GetRemoteMACAddress. (Bugs in
applications compiled to Native code are not news nor uncommon). To remedy
this problem the code below sets the call's return type as Boolean rather
than string, and fills a string variable passed as a parameter with the
remote MAC address. These mods enable the code below to be successfully
executed in either a pcode or native code exe. Anyone interested in testing
this can affect this same crash by simply commenting out the
GetRemoteMACAddress=True and =False statements, redefine the function to As
String, and assign

OK, Randy. I can confirm that this is a problem :-) It also seems to occur
sporadically in the IDE.

I'll retool and report back when I've eliminated the problem.
