When SafeOnline protection level is higher than Low the Translate Client is blocked. The client should work in a way that you select any text and clicking on icon G brings translation. For more reference how the client works, please see at http://translateclient.com/ However if SO is higher than Low the G is not visible so the translation can't be made. It looks like Prevx considers the Client as screen grabber or something like this. It occurs in Opera and IE too. Lowering Prevx's self protection doesn't have any effect. I am sending a scan log to email@example.com with a link to this thread. Thx & regards, pegas EDIT: I tried re-install Prevx and noticed that right after installation BEFORE re-boot the client works even at level High. However after re-boot no chance to work unless SO is lowered to Low. Re-boot after installation makes the difference.
