-- First, sorry if not understand what they tried to say, I do not have much knowledge in English. --
What is the problem?
In the panel "Log & Other" exists 7 tabs. Clicking with the right button on one of them and going into "Toggle" I can disable. It is precisely that the problem: try disabling two of these buttons and reactivate one. BUG!
What release of Code::Blocks are you using?
svn build rev 4943 (2008-03-10 16:17:25) gcc 4.2.1 Windows/unicode
Bye.
