Nothing is inserted when I click a drawing. Make sure the cursor is in the document body (not inside a header, footnote or protected range), and that the pane reports ready in its footer. If a drawing needs a font or character that is not available, the footer explains what is missing.
Some phonetic symbols are greyed out. A small number of legacy phonetic characters need a one-time review before they can be inserted; the pane links to the mapping page which lists them.
Can I edit an inserted diagram? Yes. It is inserted as a vector drawing group inside the document, so Word's own drawing tools (resize, recolor, ungroup, rotate) work on it.
Which Word versions are supported? Word on Windows and Mac (Microsoft 365 and Office 2019+) and Word for the web. The task pane needs an internet connection the first time it loads; afterwards Office caches it.
Support and feature requests: myhama@hotmail.com. When reporting a problem, please include the Word version (File > Account > About Word), the platform and, if a specific drawing misbehaves, its identifier from the task pane tooltip. This service is provided by Hammsoft Inc.
