Can anyone give me an idea why the following exception occurs:

Part of Debug Window output --
...............................

The thread 0xF7 has exited with code 0 (0x0).

We'll need to see the code that causes the exception. Set the debugger to
break on a Microsoft C++ exception, then past the offending code in a
message. 🙂

Normally, you can ignor first-chance exception. See Mircosoft KB.

A TRY-CATCH handler can throw such an exception and most times, its ok.

Example-Snippet:

AcGeVector3dArray * p = NULL;
TRY
{
... = p[100]; // no element
}
CATCH(...)
{
throw ... // get a first-chance exeption ("handled error")
}
