Delegate gets called sometimes from Unmanaged code

[rubino57]

Hi folks,

It turns out that in the snippet below, the MCPCallback
sometimes gets called from the unmanaged DLL. (ie. the
messageBox you see inside MCPCallback). Ths callback
is called asynchronously by a different thread from
the unmanaged DLL.

I would greatly appreciate any pointers?

Regards,
Ash
