I have Changed the login screen previously it was taking input User name, password, Base URL and topic or product as

Now at first User has to give the base URL which can be selected from one drop down box, and User name and password. like

After clicking login it will login to the base URL and if success full then it will go to the product selection page.

Then clicking the finish button it will load the bugs for first run depending on the selected product and continue with a screen

Once the bugs are loaded then and next run onwords it will go to the  main window which will show the list of bugs already downloaded.

I have added the modify option to it if one bug is selected from the  list of the bugs it can be modified with their fields and comments can  be added.

Thanks.:)
