Ha, I actually reported this very issue ca. 2 years ago (https://sourceforge.net/p/pure-data/bugs/1290/), I just completely forgot about it. what all those bugs have in common are dangling window references.

Betreff: Re: [PD] Tcl/Tk error

Hi, Christof.

I haven't been using PD much lately but I used to have that a lot. As far as I remember, it also used to happen when closing a window, specifically, an abstraction that I used to inspect signals by plotting them on arrays. When closing those windows, PD GUI would all freeze but it was still possible to change number boxes and everything else, though without having the visual feedback.

I'll get back to this if I can reproduce the bug.

hey oliver,

other users (including myself) have experienced this as well and it's a serious regression. Now that I have some time I want to investigate this. I've already fixed a related bug in September (https://github.com/pure-data/pure-data/pull/467).

can you do me a favour and file a bug report on GitHub? and can you try to find a minimal patch which triggers the problem (even if it doesn't happen all the time)? personally, I didn't have success in reproducing it, it only happenes very rarely and seemlingly randomly...
to all the other people who have experienced this: please help!

Christof
