Hi folks, I was able to reinstall an older version of IE9 PP (1.9.7916.6000) but it also raises the drag'n'drop problem. I start started debugging and found the following (Prototype version 1.6.1, Scriptaculous v1.8.3):
script.aculo.us will start dragging only if you pressed the left button (for sure ;-)). To check the the button it calls isLeftClick from Prototype which calls an internal method named _isButton (prototype.js, line 4290). This one checks whether the given button number matches the pressed button number. The function is specific for IE and WebKit-Browsers. In the IE-case it uses a LUT to verify that both button number match, since the IE seems to have a different button numbering (correct me if I'm wrong - I just studied the source). Anyway, the IE-specific solution seems not to work in IE9 PP. As a quick'n'dirty hack I just removed the according code and... voilà.. drag and drop is working again in IE9. After reinstalling PP v5 the hack still works. I propose that a check for the IE version would solve the problem in a more sophisticated fashion. Regards Steffen PS: Note, that I didn't check if the problem persists in the 1.7 release candidate.
