TYPO3 Core

i do not know the reason put same problem in ie9, put not only images also File Links.
ie console has one message. if ralated.

Element.alignToXY with an element that doesn't exist

The same Issue for IRRE Elements: #51768

Is there any possibility to get the sorting back by arrows until the drag'n'drop will work in IE?

The bug appears still in the latest TYPO3 Releases. (6.0.10, 6.1.5). Every client with IE cant sort Images or every other IRRE elements.

One temporary solution could be override the TCA in the extTables.php until sorting by drag'n'drop works also in IE:
$TCA['tt_content']['columns']['image']['config']['appearance']['enabledControls']['sort'] = 1;

Issue confirmed in TYPO3 CMS version 6.1.7 with IE version 10 (version: 10.0.9200.16750).
Editors can not change the order of images by drag'n drop.
