Hi Oded,
You should try something like that:
Retrieve the div object and store it into a variable, so you can acces to it. It doesn't matter if you use NameMapping or Find methods.
Retrieve the div object property that you have to check. For example, if you have to get the class: object.className.
Now you have two choices:
1. Wait X time (for example, a minute) and check the object class again.
2. Create a loop and check the object class every X seconds.
In both cases, you can use the Sleep or Delay methods to delay execution the time you need.
Let us know if it worked!
