The latest version of 6 crashes. Thanks, Matt

Hi Matt,

Do you have an error message ?
Seems the crash come from the TWAIN driver. I see you are using GxTwain, ensure yourself to use latest version of this tool.

Unfortunately we can not buy a Gendex XRay scanner to investigate hardware issues...

Kind regards,

Loïc
