problem with the Jquery dialog when loaded on webView

Hello,
I am using JQuery dialog to show a pop up as modal view. All is working well in all browsers. When I load it on a phone with webView, there is a wierd red color border (almost T shaped) inside the modal dialog.
Can somehow help me with whats happening there? How can I fix that issue?
Thanks.
