Yeah, that's because I did simple copy-and-paste, which includes a  
bunch of contrib libs not even used in wxPackMan. When doing  
semi-standalone it's much more intelligent about what to put in there,  
dropping the size considerably. (7.6 MB was the size if I remember  
correctly.) I should be able to trim off the extra stuff in the next  
build, but I just wanted to make sure it works first!

Since wxPython is compiled with gcc 3.1, it wouldn't work without  
MacPython anyways. ;-) I hope to have this issue resolved soon, but in  
the meantime it needs to run from Jack's installation.

Thanks, I missed that. Obviously a simple fix (check that version()  
returns something!) and will be in the next version.

Another simple fix I missed. I just need to set a selection on launch.

But does work for wxWindows apps and bundlebuilder apps using  
standalone. (Though I noticed the Apple-Q shortcut does not appear next  
to the quit menu, although it works.) I think there's an issue with  
Python itself defining the Quit menu key. I set the key for the File  
menu (which should set it for the app as well), but to reinforce this  
I'll also add it as a program-wide accelerator key.

Looks like this might be my fault... they aren't showing a transparent  
background in Preview.app either. ^_^; I'll set the transparency and  
see if it still happens.

I'll see if I can figure out the reason for this.

All except the last one (and possibly #5) will probably be a quick fix,  
so I'll work on posting a new version in the next day or two with these  
issues resolved. I'm currently working on a Panther build of wxPython  
as there is a quickly growing demand for this!

Thanks,

Kevin
