I'm certainly not convinved about that either, but we should make a test on a VM at some point. Sophos AV has plugins into for example the explorer (I assume - most AV does, haven't used Sophos specifically myself), which may be done with extra DLLs loading along with user32.dll (runtime linked) or something like that. I just want to be sure we exclude that possibility. //Magnus ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
