Helium Music Manager is using a embedded version of Internet Explorer to display HTML content such as the Music Information Browser and Now Playing/Summary in the Right Sidebar.
The embedded version of Internet Explorer shares settings with Internet Explorer itself, so if the font size somehow is small in Internet Explorer it will be small in Helium Music Manager also.
To correct this, follow the steps below:
1) Close Helium Music Manager
2) Start Internet Explorer
3) From the View | Text Size menu, select Medium
4) Close Internet Explorer
5) Start Helium Music Manager
