Can't edit project UX file fuse 0.37.0

fuse version 0.37.0 (build 12978)

Windows 8.1 x64

I just downloaded fuse 0.37, but when I open the design mode and I want to modify the MainView.ux file, I receive this message

C:\Users\MyPersonnalFolder\Downloads\send-button\MainView.ux: The process cannot access the file 'C:\Users\MyPersonnalFolder\Downloads\send-button\MainView.ux' because it is being used by another process.

When I close designer mode, I no longer have access to the project.
Please need your help

i use sublime text for edition

Thank you

the process cannot access the file is a known issue and it is currently being worked on. You’ll get notified when that’s fixed.
