My pleasure, I can't live without expr in Pd :)

Well, I'm actually doing even a bit more here. IOhannes convinced me I should also report a bug. But I've also searched all opened bug reports about expr, many were also describing same problems as I did, and, anyway, I created a new complete bug report and posted it in sourceforge.

The report links to all the other reports as well, it includes all of those issues and also other ones I'm describing.

Here is my "mega bug report": https://sourceforge.net/p/pure-data/bugs/1202/

The report depends solely on a patch I updated, with all the information in it.

I'm sending that patch attached here as well.

Hopefully it'll make all the known issues easily accessible and well organized to browse through.

Cheers
