I'm using wxSmith for quite a while. It's a great tool. But the copy and paste feature doesn't work any more recently.
What version of C::B do you use ?
Currently wxSmith is under redesign and we're working on new sources (so there wasn't any major change for about 2 months)
It should be the latest version since I downloaded nightly build version of C:B every day. But I really can't remember from which version the wxSmith stop working.
