[PD] Number Boxes, Sliders, Symbols - strange behavior (no graphic update)

Hi there,

I'm on Debian 32-bit with Pd 0.49.

I'm experiencing all the sudden a strange behavior with number boxes, sliders and symbols.

They are sending values when I click and move the mouse but their graphics do not get updated.

I. e. I can change the value on the output of a number box but its graphics are not updated anymore.

If I connect

I can see the values but the number box itself keeps displaying "0".

When I open the properties of the number box and press Apply or OK the value will be updated to the latest value but then stay there as far as displaying goes. Still sending and receiving without any graphical update.

Does anybody have an idea what is happening and how I can fix this issue?

Thanks!

Ingo
