Different size in IE9 vs Chrome/FF

[joe castle]

Hi,

The upload seems to have different size in the different browsers which affects the rest of my page's layout. 
Made the upload's background red to visualize the difference:

@( Html.Telerik().Upload()
.Name("attachments")
.ShowFileList(false)
.Multiple(false)
.Async(async => async
    .Save("Save", "Home")
    .AutoUpload(true)
      )
                    .ClientEvents(c => c
                        .OnSuccess("onSuccess")
                        .OnUpload("onUpload")
                    )
                    .HtmlAttributes(new { style = "background: red; " })
    )

The different renderings are attached. 
Any workaround for similar rendering in IE9 as in the rest?

Thanks
