By default, Automatic Mouse and Keyboard will stop the Action Script if search a picture timeout. You have two ways to make the Action Script will not stop when search a picture timeout:
1. Insert If Else Statement
2. Change the option "What to do if search the picture timeout"

Method 1. Insert If Else Statement
Double click on the search picture action to open the Search Picture dialog. Then check the option "Insert If Else Statement" and click "OK"

After Insert If Else Statement, you can insert some actions between If and Else or between Else and End If. If the picture is found, Automatic Mouse and Keyboard will execute the actions between If and Else, or it will execute the actions between Else and End If.

Method 2. Change the option "What to do if search the picture timeout"
Double click on the search picture action to open the Search Picture dialog. Then change the option "What to do if search the picture timeout" to "Continue to the next Action". And then click "OK"
