Blender 2.49b opens with all tools and menus super small - how to fix? I am using version 2.49b because my work requires it. I changed the font using "User Preferences" but that only changed the top menu. Any help is appreciated! I am new to Blender.
Go to "Panels - View all" or press the Home key on your keyboard. This  should align the panels according to the size of your Buttons window.



If you want to resize the panels manually, you can do this by pressing Ctrl and use your Mouse Wheel to adjust the size.
