#4 Hard Crash with MosChip 7703

[imcon]

COM to USB driver with chipset MosChip 7703 causes fatal immediate crash of Windows XP (tested on several machines) when we try to open the COM port via AfyncFree Delphi component.
The USB driver works without any problem with other programs (GPS software, terminal...) only AsyncFree causes the problem. No success to track the bug.
