I don't know if this is I bug or not, but when I tried to export all my configuration settings there were 2 Error messages.
They don't provide much detail only this:
Type : Export Options Error Message
Source File : [empty]
Line : 1
Description Error #1 : Numbers > Float: Error Retrieving Value
Description Error #2 : Numbers > Double: Error Retrieving Value
Creator : Export Options
That's all I get.
edit: It also shows these error messages when importing these settings onto another computer.
