There is a vanilla list column named Home Page in Account List Applet which is a URL link to external websites.
It works in our production environment and not in QA or Dev. In qa/dev when we click on that link it does nothing.
Srf is same for all the environment, I am not sure if there is any kind of setting that is differing.
If anyone knows about this please help.
When you say it works, what do you mean exactly?
Does the popup just does not happens? Do you get a little exclamation point in the bottom of the screen?
When you try Dev, QA and Prod, do you do it from the same machine (I am assuming so).
Are all the sites that your web client hit in your trusted sites in your IE Internet - Options > Security?
Last but not least, what version of IE are you using?
