I'm sorry if I didn't explain it properly. It's not in a combo box created with AutoIT. I am the Change Management Officer on a development team. I am writing scripts to perform regression testing on some of our UI's. This problem occurs on our Login screen. I scripted it to enter in the username/password and then when I choose the environment to test (eg.. Development, Integration... etc) I use up/down arrows to choose from the combo box in our UI. This is where I get the error.
This is the code I use to accomplish the login. This will enter the username/password, tab to the first combobox, arrow up to create a starting point, arrow down to choose the environment I want, tab to the next combo box and do the same thing.
AutoItSetOption("SendKeyDelay", 100)
send( "" & $login )
Send( "{Tab}" )
Send( "" & $pwd )
Send( "{Tab}" )
Send( "{Tab}" )
Send( "{Tab}" )
Send( "{UP}" )
WinWaitActive( "Login", "", 200)
Send( "{Down} ")
Send( "{Tab}" )
Send( "{UP}" )
