Hi HAIRYKIWI,

First: WOW nice script very complex! THANK YOU

the trick was actually very easy...
I wrote this line into the script: moi.ui.alert("STOP");
Than running the script. If i got the "STOP" alert before the script fault message the fault must be hidden somewhere later in the routine..
doing this step by step further in the routine i could locate these bad lines... as a fortune my script editor (TextWrangler) already marked this ".get"s as a command - so just deletet them - that was all... I'm just a hobby scripter...

I think the incompatibility of some older scripts with V4 is that it uses a newer webkit which is more nitpicking...
