Script abort - using DLL

[fspafford]

I have a script which uses an external communications Dll. The main loop of the script uses the Dll to send commands and then wait for responses. DllCallbackRegister is used to register a callback routine which processes the responses.

The script works for several iterations of the loop, and then aborts. When it aborts, it seems (by observing console output) that something is causing the the script to restart at the beginning.

I have verified the main routine and the callback routine execute with the same thread id.

Any suggestions for narrowing down my problem? I am using AutoIt version v3.3.4.0.

I found my problem, and it was related to the Dll I am using.
