If your function comments use Doxygen tags, the tags may appear bold in hovering tooltips.
The behavior occurs only if you have enabled Enhanced Syntax Coloring.
You can display Doxygen tags in plain text by setting the registry value:
HKCU\Software\Whole Tomato\Visual Assist X\<IDE spec>\FormatDoxygenTags = 00
Return to 01 to restore the default behavior.
