HELP. Level 2 Generate Yearly Report, IE POP UP Problem(can't get selector back)

Why I can’t click back on the previous working selector after clicking on the pop up save element of Internet Explorer? Even the send hotkey or type into won’t work anymore.

I know the selector is working fine since it successfully worked after numerous loop(while no download pop up showing, but after the pop up show, It seems like everything is lost.)
popUpSave|661x500

make sure the control of the window is handed back to the browser window after the pop up appears. using attach browser and a brower element throughout your workflows is a good way to ensure this

Got a fix on this. What I did is change the WaitForReady from INTERACTIVE to NONE in click activity.
