Nope, first thing you do on Intel* still hangs Code::Blocks.
This includes: compiling a file, opening a project, etc. etc.
On the plus side, Code Completion seems to be working!
(at least it didn't hang, and even completed keywords...)
* Note that this only applies to the wxMac/Carbon version!
The wxGTK version does work fine on Intel Darwin / X11.
My suggestion is to use DarwinPorts and wxGTK for now,
if one want to use Code::Blocks rather than help debug it ?
