Not launching spark messenger when created through custom application launcher
 

Hi..
I'm using fedora8.I installed spark on my machine,when i launch that through terminal,it is opening perfectly.But when i open application launcher or creating custom application on panel it was not working.
All other shortcuts like,thunderbird,firefox are opening except spark.

Please provide me sollution.....

This is .sh file.I came to know that other script files with .sh extensions are also not opening through application launchers.Only script files without .sh extension are going to open through launchers.So,how to run these scripts.

Is terminal the only choice?Every time typing the full path and launching is difficult.
