Calling NewEra DLL from Delphi

Hi, We made a DLL from NewEra source code. All NewEra functions that are exported are wrapped in C++ functions, so the 'PushArgs' and 'PopArgs' functions can be used. The resulting DLL is called from a Delphi program. We encounter the following problems: 1. Calling our own functions seems to work well, but as soon as we call a NewEra function like 'Display' the call seems to end up in an infinite loop. 2. All parameter values passed from C to NewEra using the appropriate 'PushArgs' function are set to null in the NewEra function. Hope someone can help....
