TYPO3 Core

Hi, all

As mentioned in #48800, I have an issue when moving tt_content elements on the page. At one specific column, just the first element works.

I now debugged a bit in ExtJS and got out, that the elements on the page are correctly registered in TYPO3's JavaScript code (typo3/sysext/cms/layout/js/typo3pageModule.js:294) but in the ExtJS code, when the mouse-down event is initiated (typo3/contrib/extjs/ext-all-debug.js:20854), it fails to recognize, that the mouse is over the target.

At all other elements, when I try to move the code, the mouse is over the target ...

I tested it in Firefox v22 and Chrome v27, and the bug just appeared in Firefox v22.

Here's my backend-page definition:

backend_layout {
    colCount = 4
    rowCount = 3
    rows {
        1 {
            columns {
                1 {
                    name = Slideshow
                    colspan = 3
                    colPos = 10
                }
                2 {
                    # This is the column, where the drag&drop fails in FF ...
                    name = Sidebar
                    rowspan = 3
                    colPos = 2
                }
            }
        }
        2 {
            columns {
                1 {
                    name = Content
                    colspan = 3
                    colPos = 1
                }
            }
        }
        3 {
            columns {
                1 {
                    name = Footer 1
                    colPos = 11
                }
                2 {
                    name = Footer 2
                    colPos = 12
                }
                3 {
                    name = Footer 3
                    colPos = 13
                }
            }
        }
    }
}

I don't know what could help else ...
Have you tried updating to the latest ExtJS bugfix release? I saw something of ExtJS v3.4.1.1 ....
