Prompt Dialog Tiltle is not supporting in Internet Explorer

Hi,
I am using smart Gwt-3.x.
In my application I have to show some "progress dialog box".
So, I am using the following API provided by smart gwt.

void com.smartgwt.client.util.SC.showPrompt(String title, String message)

It is working properly in Google Chrome browser, but,
it is not showing dialog "title" in Internet Explorer browser.
Please give me a solution for this issue.
please find the following attachment for reference.

Thanks in advance..
