delete from project drawer doesn't work about arcadia

[angal]

Hi, send me a detail of failed deletion (ex. /home/antonio/myfile.rb)

[angal]

can you test and close after last commit?

[rdp]

right click + "close project" on a root node [for me] yields

C:\dev\ruby\downloads\arcadia>cat close_project.log
