Re: [QF-Test] Drag and Drop HTML 5 - cannot have it working

Hi Gwen,

indeed, the interaction between the browser and Windows during the
Drag&Drop operation is blocking the event loop of the browser so
QF-Test gets stuck - in Internet Explorer as well as in Firefox.
Incidentally the same sequence works fine in Firefox on Linux.

Anyway, we're going to provide a procedure in the qfs.qft standard
library that implements this drag&drop via hard mouse events similar
to DRAG_FROM, DROP_TO, but without blocking.

For now you can use the procedure from the attached test-suite that
simulates the same at Javascript level. This may be preferable to the
hard events anyway (among other things it's _fast_) and will also make
it into qfs.qft.

Best regards,
    Greg
