newbie: script builder hangs on loading?, on update action not executing?

I'm new to Zoho Creator and was playing around with it trying to learn its features. However, I'm running into problems.
 
Problem 1: script builder hangs
I tried playing around with writing my funcition, and now
the "Functions" tab no longer works. I get a little box
saying "loading ..." that never goes away (even after several
hours, and logging out). Nothing on the page works, and
I have to close the web browser. HELP!!!
 
Problem 2: update action not executing
I created an "on update" action for my form to create a new
record when I update a particular field.
It works just fine if I update the field for the individual record,
or when I do a "bulk edit". However, if I update the record in
"grid view" and save, the action doesn't occur. Why?
 
Please help.
