I have downloaded a Smartgit 4.5.5 and trying to use in Ubuntu 13.04. But the problem is when i double click on the script smartgithg.sh it opens on the Gedit. On the previous versions of ubuntu i did not face this issues.
In the previous versions, when i double click on the script it shows me few options like 'Run', 'Run in terminal', 'Close' and so on.
here i would like to mention that the execution permission is enabled for this script. and i can run the script via terminal.
