I included a snippet of sample code [found here:
https://opensource.adobe.com/dc-acrobat-sdk-docs/library/plugin/Plugins_Documents.html ]
into my plug-in code. When executed, after the open dialog is displayed and user selects a file, Acrobat crashes. The same code compiled for Acrobat 64-bit runs without issues.
This test was performed after my plug-in (that runs similar code) crashed in a similar manner. The crash after AVAppOpenDialog started in the most recent release (2023.006.20320). The code did not crash in any of the previous versions of Acrobat.
I know I can replace the AVAppOpenDialog with a Windows file dialog - but would like to know why this is happening only in the latest release.
Any help or insight would be greatly appreciated.
