Bug on 0.64.1-32 bit


I have just installed Synfig on my PC.
As soon as I opened it, a window appeared with these words: this version is affected by a bug which can freeze my PC when I resize the canvas. Is it normal? Can I do anything?

Thank you in advanced!

It is a known bug. Just follow the instructions from the pop up message in case it happens.

Ok, thank you very much.
