The question says it all! I am looking for an easy to use alternative of blockUI for jQuery. I've been trying for days to center a dialog box with blockUI in both FireFox and IE but no chance. It doesn't work. I looked at this question about centering a blockUI dialog box (How can I get a DIV to centre on a page using jQuery and blockUI?) but it works only with Firefox.
For dialog boxes, I have switched from blockUI to Jquery UI. I think it's better.
