Canvas and Wheel Mouse Bug

Hi good day.
I detected a bug in Synfig 1.0
when I push the thumb wheel on the mouse to move the canvas, the synfig become crazy and sends the canvas to the lower right corner, at first I thought it was my mouse, and when I change the mouse initially worked well and then when I resize the canvas, resubmitted the same problem with the new mouse.

Can’t reproduce it on windows XP
Have you experienced this in other machine?

Hi, sorry I dont tested in another machine, I’m using: Linux Mint 17.1 “Rebecca” 64-bits. I try remove it, purge and donwload again and make a clean instalaltion but still presenting the “bug”, I’ll try tested in another machine to see if the “bug” persist.

I can’t reproduce either Debian wheezy (7.6 - 32b) nor Xubuntu 14.10 (64b) . I will try under a Mint live system…

Can you reproduce each time ? can you post your gtk2 and gtk3 version ?

dpkg -l libgtk2.0-0 libgtk-3-0

Hi, Thank to all you guys for the time, I format my computer and reinstall Mint17.1 64-bits, all fine, the “bug” dont appear again, sorry for the troubles, maybe something in some moment for installing and remove programs leave me some incorret think in the configuration of the software.
