if statement reformatting

I reinstalled everything recenty following upgrading my development PC to Windows 7.

When I run the reformatter over the code it mainly works but leave behind singleton if statements e.g.

if (condition)

   do something;

This should be converted to

if (condition)

{

   do something;

}

according to my settings.

I've tried all the recent 4.5 builds as well as 4.1 and get the same result - any ideas?
