LANSA Composer help doesn't open when using MS Edge as the default browser

Date: 19 July 2016
Product/Release: LANSA Composer - V6.0
Abstract: After Windows 10 update, Microsoft Edge does not always open LANSA Composer help when F1 is pressed.
Submitted By: LANSA Technical Support


This issue affects LANSA Composer V6.0 on Windows 10 with Microsoft Edge version 25.10586.0.0 as the default browser. If an instance of Microsoft Edge is already open, pressing F1 to open the LANSA Composer online help do not open correctly.

Note: You may not observe this issue if your Microsoft Edge browser version is not version 25.10586.0.0 or greater. Microsoft Edge is updated to version 25.10586.0.0 via the latest Microsoft updates.

About this App Edge Version

If the default browser is Microsoft Edge (version 25.10586.0.0) and an instance of Edge is already open, then a new Edge window opens but it does not navigate to the required URL for the online help/docs.
For example, if you have already pressed F1 on SMTP server configuration in LANSA Composer and you now press F1 on POP3 mail, this time the help doesn’t appear and the browser home page is displayed instead.

Example of the Edge home page being displayed instead of help
If no instance of Microsoft Edge is open (or another default browser is being used), it works fine.


After applying the hotfix, when Microsoft Edge is the default browser and the help is being accessed from a locally-installed copy (as is the case in LANSA Composer 6 as shipped), the help will open in Microsoft Internet Explorer instead of Microsoft Edge.

After the hotfix is applied, multiple instances of help in Edge can be opened
