    Default Unanswered: Grid scroll not responsive on IE8 - Windows XP


    I have a grid that loads 100 records at a time, until all records are loaded, and appends to a grid. The store associated to grid is a memory store, that merely just holds data.
    When records loaded in grid are over 1000, the scroll on the grid becomes extremely slow and does not respond, and IE8 hangs post this. This is on a Windows XP machine.

    The same works fine on IE8 on windows 7 and above.

    Any thoughts on this will be of great use for us to debug this issue.

    (We are unable to use buffered scroll/Infinite scroll as we have customised grouping, streaming integration etc,
    which dont go very well with infinite scroll.)

    Sounds like the browser is choking on the number of items you have rendered.
