With old version of bitcoin clients I can easely connect to bitcoin network using tor, but after upgrading to 0.8.1 I can't see any connection in client. Is it some bug, do somebody else have the same problem? I use windows client, win7 32bit.

Solution:
New tor browser use 9150 port to connect to tor network, so just change default port value in bitcoin client from 9050 to 9150.
