Local installed design studio freezing whil editing script

Hello All,

         I have installed the Design studio version 1.3 locally in my laptop.

         I opened the application in design studio. When I try to edit the script the tool freezes and

         I have to stop the tool and restart it again.

         My laptop has 4GB ram.

        Can anyone please help to come out of this issue.

        Thanks in advance.

Regards,

Anwar
