Having trouble with the OK button functionality on a JavaScript confirm popup in IE11. For one user, clicking OK doesn't work - nothing happens. It works for most other users though. Normally, clicking OK should close the popup and trigger the event handler for the btnSave button. But in this case, the popup doesn't close after clicking OK.
I suspect it could be an issue related to settings in IE that only affect this particular user.
Here's the code snippet causing the issue:
btnSave.Attributes.Add("OnClick", "return confirm('Do you want to save?')");
