It will work as you want if you customize mouse-drag-copy-region to a
non-nil value, I think.

I will try to fix the default case as well in a few days (let me know
if you want meanwhile to try a fix -- it's in mouse.el), but no
promises, since this is all very tricky due to conflicting
requirements and the fact that Windows doesn't have primary selection.
See, for example, bug#6689.
