SVN r6906, Win7_64
In VISIBLE part of Code, minimized functions are self-changing [ + ] to [ - ], BUT STILL minimized,
when CodeBlocks window is backgrounded (when I googling or running project app) some time
(I can't determine conditions more accurately).
So when you clicking [-], function is just setting UNDERLINE (like on "minimize" ),
instead of "Open minimized code".
I repeat - this bug present ONLY IN VISIBLE PART of Code-window!
Minimized functions above & under visible part - aren't changing [ + ]
