I wish to write a modal dialog box for my project, similar to this http://obout.com/editor_new/howto_sc.aspx.Which is very simple:When a user click on a button,the page will make a call to a web service and when it is done,a Movable Modal Dialog box will show and populated with my data, along with buttons and scripts for those buttons.It seems that the panel and popup extender can show the popup but it is not movable.Should I do it with AJAX tool kit or using pure Javascript, I see a few sample on the web, but it is kind OF complicated.

When using a modal popup extender along with an embedded video, the popup is hidden behind the video in IE but works as expected in FF.I've tried manually setting the z-index of the popup to a huge number and the z-index of the video object to 1 but this makes no difference. I've put the code for a sample page below.
