I have a 6.0.7 Debian4 OSS install.
It seems I cannot make DnD work in any way.
At upgrade time I had dnd and dndext zimlets installed.
Then I undeployed boths, and redeployed dnd.
I see the "Drag file here.." tooltip, but there's no area in the screen where I can drop the file to make it work.
I tried all possible browsers on linux, no way.
On Windows, in Firefox and IE I don't even see the tooltip. With Chrome I can drop files and attach to mail, even if it's quite tricky...
Could the dndext have caused this on upgrade?
