visual studio 2010 - Can't collapse pieces of code after doing Ctrl + M, P -

-

ctrl + m, p expands whole document. after doing can't collapse specific methods or pieces of code. it's not possible via shortcut keys (for example: ctrl + m, m) neither via menu:

as can see, ctrl + m, o possible collapses whole document

only <code>ctrl + m, o</code> possible

also + en - signs disappear when ctrl + m, p

in vs2012 toggling outline expansion [ctrl] + m, m. presume hasn't changed previous version. don't have vs2010 check...
