I tried setting the SendWindowsMessages as you suggested, but that does not help.
I still get the same error message.
However: with SendWindowsMessages on, and Occurence set to 1 or Occurence set to 3 with a broader selection that contains all 3 “Amounts”, it works like a charm.
So, I digged a little deeper and deselected the SendWindowsMessages checkbox (with occurence set to 3 and the broader selection): it still worked.
Then I noticed that today IE opened on my big screen (with the 3 amount fields visible on screen), whereas last timed it opened on my smaller laptop screen (with het 3 amount fields not visible on screen).
So I tried it on my laptop screen again, and … there’s the error again.
So I suppose visibility plays a role in this?
Thanks for clarifying this one.
In my opinion it is not always clear what is meant by “in the background”. I thought it meant “application is up and running”. Well, IE is up and running… I never would have figured out that it could also mean “not visible”.
