    Just installed the latest Opera 8 in a new folder and in parallel to my existing Opera75 (Win2k-SP4)

    1.) Application filtering detects the new app and asks for permission. So far, so good! However, my Internet filtering in LnS does not distinguish betweeen the 2 versions of opera.exe ??
    So does this mean that one can create a malicious program with the same name as an already allowed application name (located in a different subdirectory), and LNS would give full access to the malicous file according to the rule originally made in the internet filtering??

    2.) Opera 8 is supposed to be the fasted browser (according to what others currently observe). But when using LNS I always get one initial block of outgoing connections made by Opera8 in the internet filtering. This dramatically slows down the speed of Opera so that I cannot use it :(
    Firefox or IE do not show this behaviour...

    Any other Opera users out there to confirm ??

    Thomas :)

    Ruben,
    Thanks for your reply!
    Regarding my first point: Did you make a parallel installation of Opera 75 and Opera8, or did you install the latest version on top of the old one? My LnS does not detect the different opera.exe files in internet filtering. It seems to me that internet filtering defines the old opera.exe the same as the new opera.exe (which is not true!)

    Thomas :)

    I just installed version 8 straight over the top of version 7 with no problems whatsoever.

    Sorry I didn't read your post correctly - I installed on top, so your observation might be true. My remarks were meant for the timeproblem you described.

    OK, the initial outbound blocking problem seems to be specific for my machine :(

    Thanks Ruben and Tony :)

    Hi Thomas,

    Are you talking about Internet Filtering or Application Filtering ?
    In case of Application Filtering, normally since the path are different Look 'n' Stop should consider two different application.
    On the Internet filtering side, it relies on the Application Filtering authorization.

    Regards,

    Frederic

    Hello Frederic,
    Thanks a lot for your reply! I was refering to "Internet filtering". Yes, "Application filtering" detects both versions of Opera. This is good :cool:
    However, I expected to see both Opera.exe versions also in Internet filtering, since I could try limiting a specific rule to ONE defined application only. Unfortunately I do not have any example for a malicious application that could use this feature to do some bad things on my machine: Since both opera.exe files must be allowed in Application filtering first, there is no way that they start a connection without my knowledge. But fact is that I can not control different applications with the same name on the Internet filtering level, e.g. prevent a connection from a specific port or IP. Is there anyone out there, who could think about a possible szenario, where this could become a problem?

    You all have a relaxing Sunday :D

    Thomas :)
