We're currently investigating an issue that is causing HelpMaster to freeze/hang when using the Action screen.

It seems to be related to the spell-checker and/or the auto-save feature that the action screen uses.  Periodically, the Action screen will save the contents of the action details textbox to a text file located at  C:\ProgramData\PRD Software\HelpMaster\AutoSave\

It seems that machines running Microsoft Defender can sometime hang during this save.  Adding an exception in Windows Defender avoids this issue.  The exception can be either the path, or the HelpMaster executable file.

We'll continue our diagnosis and testing on this issue.  If anyone else is getting this behaviour, please let us know.
