Summary: divide by zero when scrolling patch window
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.
