https://community.blueprism.com/t5/Product-Forum/Internet-Explorer-Attachment-behaving-wierdly/m-p/72788#M25393 Is this a timing issue where you are trying to attach before the new window is available? I recommend either using the environment utility object action that waits for process window or amending your attach logic to loop around attempting to attach for a set period of time (the later can also be modified to attempt different child index numbers just in case this is a multiple process issue) Tue, 31 Oct 2017 19:43:00 GMT Denis__Dennehy 2017-10-31T19:43:00Z https://community.blueprism.com/t5/Product-Forum/Internet-Explorer-Attachment-behaving-wierdly/m-p/72787#M25392 Hi , We are facing a problem while attaching to Internet Explorer(Version 11), this is intermittent. Scenario: Firstly we open 2 different applications in two different IE. Then from the second application while clicking a link, new window opens in the same IE as second TAB(here a third party content viewer also opens separately) which we need to attach to Business object for processing. This fails intermittently. The parameters used for attachment are "Window Title" and Child Index as 0(when we give child index as 1, it is not working at all, ideally this should work as the IE tab is the second TAB which need to be attached. Also, we have used Activate Window appropriately when we toggle between the parent 2 application. Any suggestion?
