[Update:Resolved] Opera compartible troubles

When I open demo on http://www.fckeditor.net/demo using lastest versions of Opera
Opera/9.64 (Windows NT 5.1; U; ru) Presto/2.1.1
Opera/9.80 (Windows NT 5.1; U; ru) Presto/2.2.15 Version/10.00 (new installation)

There is an 'freezed' insert-edit link dialog: only tabs appeared, if I click on any tab form is appeared, but not translated and not filled (if I edit link)
'freezed' browse server dialog: browser opening, but resources types list is empty and file list is empty.

Can anyone explain the course of it situation and how to fix it?

Update

It was fixed by adding opera depended condition at line for browse server dialog
<frame name="frmUploadWorker" src="javascript:void(0)" scrolling="no" frameborder="0">

And adding opera depended condition for line
document.write( '<iframe name="UploadWindow" style="display: none" src="' + FCKTools.GetVoidUrl() + '"><\/iframe>' )
For link edit dialog.
