jQuery modal dialog focus automatically goes to "Close" button -

i have jquery tooltips bound $(document)

i opening modal jquery dialog , loading content via ajax, resizing , centering dialog once loaded im having following problem:-

when open modal dialog, focus jumps straight "close" (x) button in top right , tooltip "close" pops , because window being resized once content loaded, tooltip never disappears , ends floating in middle of dialog.

i have seen this post same problem, , solution fine, cant seem find event host $('close-button-selector-here').blur(); method call.
