IE COM get another window

[euras]

I have a problem when I try to click some button in one window, which leads me to another window. The problem is getting the second window. My method works only if the new window will be opened sooner then sleeps ends, if not, most probably I will get an error message that variable was not found, so I think the loop doesn't work. Maybe someone can look at my code and give me advice where I'm wrong and how to fix it to have a smooth moving between windows?

Code: Select all

pwb := IEGet("Service")
pwb.Visible := True
pwb.document.getElementById("contentIFrame0").contentDocument.getElementById("gridBodyTable").getElementsByClassName("ms-crm-List-Row")[0].getElementsByTagName("a")[0].click()
Wait(pwb)
Sleep 1000
Loop{
    pwb := IEGet("Service")
    sleep 100
    tekstas := pwb.document.getElementById("contentIFrame0").contentDocument.getElementById("OverviewTab_header_h2").innerText
}until (tekstas != "")
