if not find Error

your find() seems to raise an exception, instead of coming back with None (so your code would have worked).

place
setThrowException(False)
before your code. this tells the find()'s to not throw exceptions.

I learned, that with 0.9.8 the default for this flag is False - yours seems to be true ???

Are you sure, you are running the latest version?

Hi Raiman, this worked! Thanks!

I'm not sure why my default is True...I was using 0.9.7 but will upgrade to 0.9.8 to see if the default changes or my installation was corrupted. Thanks again.

Need: to find the image which appears for some time and will disappear. People Andrey - login in chat and logoff, need clicked on nick.
Question: How to make search of such image? While not find (img) - doesn't work, because quits the program if doesn't find the image.

def clickAllPeople ( ) :
 while find( <imd>): # While open program games
   popup( "open cycle programm")
   peopleAndrey= find( )
   if peopleAndrey:
    click( )
    click( )
    type(Key.Enter)
   else: # THIS IGNORED CYCLE :(
     wait(1)
    popup( "end cycle programm")

switchApp("clickAllPeople.app")
sleep(2)
popup("start")
clickAllPeople ( ) # 18Line - this error Type 2
popup("end")

How this worked:
opup windows:
a) Start
b) open cycle programm
c) Error on line 18

Problems:
1. Ignred cycle , if not find image!!!!!
2. Exit from program on 18 line :(
Error Type 2:

Add: The reason of an output from the program - this line because the image isn't found

Use exists() instead of find.
