It appears this is definitely linked to the amount of data exchanged between Pd and Tcl/Tk and apparently sliders are relatively hungry GUI-wise as their presence definitely increases frequency of this occurence. What is particularly curious is the stderr feedback. The moment gui loses ability to sync following objects stop responding:
hradio vradio vu hslider vslider number2 and old number objects
curiously bang and toggle remain operational
You can try to type in the old number and the first digit followed by ... appears but it never updates.
The system remains responsive even with gui stuck (data is still being passed through objects that appear stuck).
stderr shows last command that causes problem as: missing close-brace
which suggests to me that perhaps messages flow so fast to tcl/tk that it perhaps some of them get mangled and lose the closing brace. The patch in question uses only following gui objects: number2/number/toggle/vslider/bang/canvas.
Any ideas?
Best wishes,
