error 10091
Discussion Open
In MindManager 2024 (Windows), WWB-COM macros throw error 10091 when trying to perform even basic operations on topics — e.g. .Select, .Text, or .Notes — even on topics created via AddSubTopic.
Creating a topic works fine, but any subsequent operation on it fails with error 10091.
Could you please advise how to resolve this issue?
