Hi,

I am more of a casual user then Pd expert, and what follows could be just plainly wrong...

The symptoms: while editing text in object/message boxes I often experienced (what seems to be) a buggy behaviour -- the apparent bug is usually only annoying, but it is also capable of forcing Pd to crash.

The remedy (attached): a small patch over rtext_key() of g_rtext.c.

Now the question: am I supposed to report such findings through pd-list, directly to the author, or anywhere else?

Best to you all,

Krzysztof Czaja
