Problem with 2.3.0 version and "Mid$" function json_BufferAppend

[soerenGer]

Hi,
I just upgraded from 2.2.3 to 2.3.0 hoping we get hold of some strange performance issues which sometimes kicks in.
The method "json_BufferAppend()" however runs into a error at run-time (not compile-time!), "run time error 5, invalid procedure call or argument". Looks like this has something to do with the "Mid$" assignment, I am a little dazzled about the commend here, which seems to exactly state this ;-)

' Note: Namespacing with VBA.Mid$ doesn't work properly here, throwing compile error:

Not sure about the exact issue as VBA is not my core strength.

My environment is Excel 2010, 32 bit.

Regards,
Sören
