Problems with Enterprise Mode (IE Mode) in recent builds ?

We are using the Enterprise Mode Site List to open specific internal pages using the IE rendering engine. (Primarily for our ERP app which requires Java Web Start... Not supported under Chrome / Chro...

Hi jpochedley, Kelly_Y directed me to your post as we just started seeing the same issue.  My full post is here:
Edge Beta intermittently ignoring IE Mode - Microsoft Tech Community

I can reproduce the issue randomly if I keep loading the same site on new tabs in Edge Beta or Edge Stable.  The key is I have to keep opening a new tab and paste the site in the address bar and just keep doing so until one fails.  So Kelly_Y  if you could let me know which types of logs or traces you need, I can start working on those.  Do you have any documentation on that?  Thanks!

I concur. The method you mentioned... just keep opening new tabs to IE mode sites, over and over, until it fails.... is the only way I can regularly repro the problem too...

I did open a case with MSFT... Unfortunately they did not reach out to me until 5 minutes before EOB for the day. (Of course...) So, I requested a call first thing in the morning on Monday.

In the interim, if Kelly_Y can provide details on what logs I can collect before the call, that would be helpful!

    jpochedley SteveSta  Hello!  I'll pass on your observations and how you folks were able to reproduce to the IE Mode team! 

     

    jpochedley Thanks for opening a support case!  But sorry to hear about the bad timing! :sad:

     

    I'll check with team now to see what type of logs they suggest would be helpful.  Thanks!

      Kelly_Y We opened a Premier case as well, but still looking forward to you sharing which logs would be best to provide.  Thanks!

        Found in testing that if a site doesn't load in IE mode on a tab, that tab will never load it in IE mode, nor will it load any site in IE Mode.  It's almost as if that tab doesn't know what IE Mode is.  You have to open a new tab and try again on that new tab and hope the new tab works with IE Mode. 


        The opposite is also true, once a tab loads a site correctly in IE mode, any site that is in the XML list for IE mode will work on that tab, even if you use that tab to go to a non-IE Mode site, that tab will leave IE mode for that site as expected, then if you go back to a site on the XML list it will load IE Mode as expected.  Issue seems to be related to the tab itself.

        I shared this with the engineer working our Premier ticket.

        jpochedley Do you happen to see this behavior as well?
