Windows 7 x64 - GTX 580 3 Gb x2
Broken: 2.72 x64 official
**Short description of error**
As title says.
**Exact steps for others to reproduce the error**
- check "Show Header" in User Preferences -> Themes -> Properties (Theme Panel Color), you can see the header
- click on Save User Settings
- close/open Blender, "Show Header" is unchecked.
And with Unbutu Ambiance Theme, "Show Header" is checked by default (but with Alpha at 0 so no visible) and after clicking Save User Settings and close/open Blender, "Show Header" is unchecked.
