see my recent post on this subject... and
the responses...

it sometimes takes several or MORE! tries
before the panel organizer realizes you
really want to drop it there!

someone said drag it to the folder icon instead of
the folder name... also you can try dragging and
dropping real slow... and make sure you are right
in the middle of the row when you let go...
i got it to work well enough...

also you can re-calibrate your touch screen in case it
is slightly off....


good luck!
