Drag from Grid (in Iframe) to Tree (in parent) in Firefox

I have my grid in an iframe and tree in my parent page and when dragging and dropping from Grid to Tree in Chrome all is well.

But in Firefox (v12) the drag wont drop!

It seems to work if you select the row and then unclick the mouse, the row stays “stuck” to your mouse as though you are dragging but when you click onto the Tree item it does not drop. The tree “recognises” its there by showing the line or background colour to tree item it hovers over but just wont drop. I have tried clicking the tree item but i wont drop the dragged grid row!

Any help would be great!

Chrome - works great.
Safari - works great.
IE - not yet tested but has worked great in past…

Thanks

Unfortunately it can’t be fixed ( worked for older FF versions, but do not work in modern ones )

I’m not sure is it a feature or security restriction, but in FF, mouse action which was started in one iframe is not detectable in other iframes, so js code just can’t detect mouse actions in other iframes while mouse button is not released.
