These fixes are similar to #122. I tested the code using Opera 8.50, IE6, FF 1.4.

(In [1609]) applying (modified) patch to fix drag and drop in Opera. fixes #122 and fixes #123

I agree that enabling e.preventDefault() on mouse down event is bad. But without it drag operations produce chaotic selection in Opera. I'll try to investigate how to deal with it.

BTW, one possible (and completely safe) solution is to have drag handles. It looks like that was the original idea (API is there) but no code to support it whatsoever.

I'll reopen this bug to track this issue.

I enabled e.preventDefault() to see what breaks and I don't see any problems. I tested Opera 8.50, IE6, FF:

1. I can click links in drag sources without problems.
2. I cannot select text in drag sources --- it causes dragging.

I think it's how it's supposed to be. Could you verify that? If you see any unwanted side-effects, please tell me, so I can look for them and fix 'em.

sorry

This has been fixed by renabling e.preventDefault on mouss down over drag sources. This can present some undesirable behaviour for complex drag sources, for example if they contain text that should be selectable.

Marking as fixed for now, by [1667]
