BJB2, ListControl and Native code

Nasty one here...
I'm running Borland Java Builderr CLient/Server v. 2.
I've got Borland C builder Professional (1 and 3) and NT 4.0.
I've got a very simple jave program that loads a DLL (System.loadLibrary("")) and then tries to create a borland.jbcl.control.ListControl.
It does not RUN under BJB2, but I can DEBUG it and it works fine. If I try to execute it from the command line, I get a floating point exception and the program crashes.  If I don't load the DLL, it works fine. The DLL contains only a single summy function.
Under BJB, it works fine.
I hope someone out there has come across this one and knows a fix (not using the ListControl is not my favourite option, cos it's  just hiding the bug).

I think BJB uses some other DLL also apart from the one or more DLLs you are using to get the ListControl functionality. This is the reason it works in the BJB environment and crashes otherwise. I have a simple utility (I can e-mail it to you if you need) which will detect all DLLs or libraries a particular DLL requires. With this you will be sure if all DLLs are included. If you load these required dlls you must be able to work fine.

Even if it does not, have the points for the utility alone!
