And check the font dropdown
I hit post too soon but was able to edit it in time. Reload this thread and see if it answers your question.
Figured it out by accident.
The test settings dropdown list on the tool bar was set to 24pts anytime a new dialog is created.
Apparently LabVIEW remembers whatever value is here.
[EDIT] We were posting at the same time. You are right... that was it.
