So in my code I have two link that i need to click function testclicklink() { Click(linkx); Click(linky); } if i open new browser and run this function, then it working, but if I was on different tab and want navigate to linkx and linky then it failed to find the object. Some time it click on (linkx) and it can't find (linky), but some time it failed both. Re: Window 10 IE getting window inactive or Cannot Activate the items Yes I follow all the IE browser setup step and disable Superfetch. https://community.smartbear.com/t5/TestComplete-Functional-Web/Window-10-IE-getting-window-inactive-or-Cannot-Activate-the/m-p/154992#M31255 https://support.smartbear.com/testcomplete/docs/general-info/configuring/windows-specifics.html#testing-on-windows-10-and-later-operating-systems but it not resolved the issue. After some testing and debug with my co-worker this is what I see the script is only working when I open new IE browser, but if the browser is already running then the test is failed because it can't find the Object. Re: Window 10 IE getting window inactive or Cannot Activate the items First I was running testcomplete Version 12.3 and IE11.674 but I test keep failing, so I downgraded my testcomplete version to 12.10 and it still failing. Window 10 IE getting window inactive or Cannot Activate the items After updated to Windows 10 i am running to this issue in the middle of the script. I am getting the error "Cannot activate xxx item" or "The window is invisible and thus cannot be activated". I try other machine with window 7 and it working. I also trying this and it not working. If anyone have any solution please let me know "The Superfetch service sometimes preloads Modern UI applications to memory and keeps them in a suspended state. When TestComplete checks on these applications (for example, when updating the object tree), they are started and get focused, which may interrupt your test run. To prevent this, disable the Superfetch service by using the services.msc application. You can also enable support for Windows Store application testing only when you need it and disable it when you need to test other applications on Windows 10."
