I have the same problem - only the timing is slightly different. My TW client freezes for 10-15 seconds befor working again for three to acht seconds. All clicks and key presses I make during the freeze are executed immediately after the unfreeze. Both client and server are running TW12. The client is a 5-channel corporate license (here at work), the client is a free non-commercial license (my private home PC). Is there any way to find out what causes these intermittent freezes? It started out of the blue after working fine for months, and it has gotten to a point where all but the most basic interaction with the target system is practically impossible.
