Dear list I am currently developing a big patch for a piece.It uses a lot of graphics objects for the GUI and this is separated from the audio process by using [pd~] object.I run the GUI from an abstraction which I open with|vis 1 (|[sendcanvas]the patch works with no problem, except sometimes when I open the abstraction and I close it again, I get the following:(Tcl) INVALID COMMAND NAME: invalid command name ".x55bd8cfa9d70.c"while executing"$tkcanvas itemconfig $tag -text $text"(procedure "pdtk_text_set" line 2)invoked from within"pdtk_text_set .x55bd8cfa9d70.c .x55bd8cfa9d70.t55bd8d8d3360 {60.96}"("uplevel" body line 10)invoked from within"uplevel #0 $docmds"in Mac 10.10, this completely freezes the GUI (faders mainly) while on Linux it works better but eventually, it freezes the GUI after opening the window and closing it a couple of times.there are a lot of messages coming back from [pd~] using [stdout], this flow of data is interrupted first before closing the window, but I still get these errors.
