--- Comment #28 from Stefan Dösinger stefan@codeweavers.com --- You can use winedbg to enable and disable log channels while the process is running (attach the debugger, "set - relay", then later "set + relay"). Note that the process has to be started with WINEDEBUG=relay for this to work. So you have to turn it on, then off, then back on again.
That assumes that the copy protection doesn't decide to terminate the game because you have a debugger attached...
