Webtemplate saving problem!

Hello,

After i modify the webtemplate, when i try to save it..

<b>Status bar: Saving Template 'zmytmplate'.....

WAD Title: BEx Web Application Designer (Not responding)</b>

This situation remain for the long time. I had to close the application using taskmanager, and end the process. I am able to save this, opening the same once again.

why it is happening...any ideas?

thanks
