Win32:IEautomation script hangs after displaying popup window.

1)if this stuation occur then use following solutions:
a)After displaying popup window,it doesn't load page completly,thats why its goes into infinite loop.
so copy exists function and create one more function for click() like ClickWithoutWait() and remove WaitforDone line from this function.
Use ClickWithoutWait() function for displays popup window.
