$@ in msg box probably still crashes when incoming args > 1000 (same with pd-extended)
The only reason I implemented $@ was because you asked me to and then spent a couple hours making sure it worked on the new code base. I don't use that feature and apparently no one else does (since regular pd/extended don't even have it), so if anything this should not even be advertised as a feature... That said, you're absolutely right--this is a bug and I am glad that I am actually getting at least a few bug reports as a result of my provocative statement :-)
