After start of Visual studio 2013, I have opened tabs class1.cpp and class1.h, class2.cpp and class2.h... When I press Alt+G in class1.cpp it jumped to class1.h file (correct), but then the file tab is moved to the right as preview tab (incorrect). It does only after start. If I first click on class1.h so the contents of the file is loaded, then it is ok and file tab stays on the place after Alt+G from class1.cpp.
