wxExecute problems on first start...

[MortenMacFly]

Do you think this is the problem caused by wxExecute?

Maybe, you can try to comment the portion where the compiler is called to obtain the macros.

Code

Manager::Get()->GetMacrosManager()->ReplaceMacros

Does this function thread safe?

I don't know, to be honest. But I doubt its the call from CC that fails - the compiler cannot replace the macros. For CC it seems to work, otherwise you wouldn't have CC working properly.
