Bidule as Rewire Host in BWS

[digitalfix]

Has anyone tried this the other way round using ReaRoute to feed Bitwig into Reaper? I'm trying to get this working but when I press Play in Bitwig, transport shoots off at a crazy fast speed.

Edit: I've just tried this in Live as well. Seems to be a ReaRoute issue as it's doing the same there as well.

Edit 2: This was happening because I was running Reaper as an Administrator. Bitwig could really do with being a ReWire Slave without the daft restrictions Live has.
