Do Not Apply any style system wide fonts - constantly gets reset to false

There are many WindowBlinds styles that modify system fonts.  In most cases this is not an issue. However Microsofts's Visual Studio Development Environment crashes when this is attempted.  The ability to disallow the modification of system fonts (see title above) is the perfect solution.  However, once set and applied, the value is reset at odd intervals.  i.e. it may hold for a week, and then mysteriously get reset to its default value - that is to allow system fonts to be modified.   There are many styles that  automatically adjust system fonts unless this parameter is set.

Please fix this....
