I would test the old version to see if the behavior has changed, in
any case it would be something that wxWidgets has changed. It may just
be that when the menu is removed the accelerators are removed too. You
can supplement or replace them using a wxAcceleratorTable.

As explained in the code you've seen, there are many things wrong with
allowing it, the least of which is that you definitely cannot call
coroutine.resume() from the event handler in the coroutine.
Search for "cannot resume non-suspended coroutine" here:
http://wxlua.svn.sourceforge.net/viewvc/wxlua/trunk/wxLua/modules/lua/src/ldo.c?revision=100&view=markup

The worst is that wxLua can't tell when a coroutine is collected so
wxLua will crash if an event handler is called into that coroutine.

Please read this thread to understand a little more about why it was blocked.

The issue is that doing this is dangerous and sometimes you have to
stop people from trying to shoot themselves in the foot.

How exactly are you using the coroutines? You're creating one to run a
Lua script and somehow debug it. Can the wxFrame live for longer than
the life of coroutine?

This is for ZeroBraneStudio? How do I run it and where is the code?
There seems to be a lot of binary files there. Where is the code that
uses the coroutines?

Deal?

Ahh... Ok, you get the error messages from the coroutine and not the
main lua_State, this is right.
