Button calling function import works in chrome but not in internet explorer

Hello,

I have created a button to call function import which basically sends an email to the selected recipient. I'm seeing a different behavior in IE compared to chrome.

When I click the send button multiple times the email is sent multiple times in chrome. When I do the same in IE the email is sent only once i.e. the first time.

I have placed a break point in the back end system and noticed that the calls are not happening in case of IE. The calls are made every time I click the button using chrome.

I have debugged this in both browsers and the function import returns an OK response in both cases.

Has anyone faced this issue before.

Thank You,

Kabir
