Initial Comment: Hi,

Sometimes, when scrolling a big patch window full of a lot of gop-enabled abstraction instances, BY MEANS OF THE SCROLLING WHEEL OF THE MOUSE, an error message dialog pops up, titled "Application error" which says "Error: divide by zero". If I click on "details", it reads the following:

"""" divide by zero divide by zero while executing "expr -abs(0)/0" invoked from within "pdtk_canvas_scroll .x9a4e60.c y [expr -abs(0)/0]" (command bound to event) """"

Pd does not crash nor hang, it keeps working even while the dialog is open, and it keeps working when I close the dialog by hitting "OK".

It happens apparently at random times, but if I do a lot of scrolling up and down and up and down i'm almost sure to reproduce it within less than a minute.

It seems it does not happen when scrolling by dragging the scroll bar, only when using the mouse' scroll wheel.

And I guess it only happens with huge patches full of gui, as it had never happened to me before.
