I dont think that is it. I am using IBO 4.5A? with FR 3.14 with
no apparent problems. I am fiddling with FR 3.16 now, since I
see that they have some extras that I do want (CSV export etc).
So far I have no problems.

Again I suggest that the debugger should show you a call stack
and so help isolate where the problem is being generated.
