Francois I don't see any issue even with the files you shared. Nevertheless, Please try the following options: 1. Reset user settings by going to SpaceClaim options > Advanced > Reset All User Settings: 2. Clear contents of %temp% folder. 3. Rename the SpaceClaim folder located at  %APPDATA% to SpaceClaim.old. Close all open SpaceClaim sessions and start a new session. Please let me know if this helps.   Regards, Gaurav
