    Howdy! Outstanding, very impressed with the new version. But I seem to be having trouble downloading it — every compressed .ZIP appears to be corrupted or otherwise unopenable. Anyone else having this problem? Tested and reproduced on 2 different machines…

    I also tried to download multiple times ZIP files of jQuery UI, stable or custom and I got corrupted archives as you Nathan…

    I hope this will be fixed soon !

  3. I am also having a problem downloading. The file that gets downloaded appears to be corrupt. I am attempting to open it in WinRAR.
    The message I’m getting is “Unexpected end of archive” when opening the zip. I can see the development-bundle folder and the index.html when I attempt to view the contents of any of the files, I get “The archive is either in unknown format or damaged”. I hope this help you troubleshoot the problem.

    Hi, any idea when new features / 1.9 stable comes ? Jquery UI is great, but it takes ages to get it complete and consider using it as a default ui js library such as ExtJS or qooxdoo.
    Sure, philosophy is not the same, but at an enterprise level, we need a global set of functionnalities, and I find difficult to brand nice products with jqueryUI (table grids ?) and each time I need to select One library for making a UI job, I can’t select jqueryUI because of severe lacking elements
    On the other hand, jqueryMobile is getting more attention and grows ten times faster, that’s a pain.
    Don’t get wrong on my position, I know we are talking about an opensource project and it’s difficult to get resources, but it is now more or less 2 years I see “tooltip” > coming soon and I really beg if jqueryUI is not loosing timeline war by providing good solutions to common problems too late.
    Sure the maintenance work is great, but missing pieces should come very soon to meet interest and success in the community.
    By the way, jqueryUI team deserve all my respect for the effort
