[letitbezh]

thank you for you answer ，what else you will need?

[corelanc0d3r]

just to rule out some things - would you mind trying the latest mona.py version (r577 or up) & see if that one fixes the issue?
If not, I'll have to set up a system with the application you're using, to see if I can reproduce.

What language is your system in? What are the system locale systems ? (keyboard, etc)

thanks
