SMKOL  the re-configuration of Privoxy is completely accessible from the Privoxy Utility(which is a seperate drag-and-drop app) - any alternations to the default settings should be accessible there first and then if you enable the web alterations then you can configure most things through the browser. The current installer will also attempt to copy your current config files and list them as .old and so on in the utility. You can switch back and forth and copy and paste. However if you version is old it might be smarter to start fresh with the new one and add things as you go forward. In my experience a lot of cites that required custom steps to make work now just work.  
(Version 3.0.10)

SMKOL  solved it myself - turned out I had to re-install quicktime(!). I don't know why but I also found I couldn't play movies I knew I could before. That lead me re-install QT and then I just tried the debug menu again and it worked! Now isn't that odd!  
(Version 3.0b)

SMKOL  Since 10.4.10 (uninstall Safari 3.0b, update with combo, reinstall Safari 3.0b) I cannot run the Debug menu.

If i turn it off, it comes up; if I turn it on, it stops half way loading the first page.

Anyone else?

SMKOL  the problem is the all drives fail eventually. A key distinguishing issue is whether the bad blocks are new or old. If they already have data then presumably they are new bad blocks. I think that would be a way of increasing the warning level. Unfortunately it's not a way of general checking a large more or less empty drive.

We generally write zeroes across drives as soon as we can to give the drive a full coverage and a chance to reallocate blocks the first time to settle if blocks are new or old. Later if we run into a drive that has a delay writing zeroes again (we're in a situation where we re-image large numbers of computers annually or so) then we KNOW its a dying drive just because we've got history.

I don't know if you can build a kind of background write zeroes or ones into the system when idle without saving a file - or writing a file and mapping out sections of the drive until eventually the whole drive is covered - or even if its knowable that certain manufacturers do some write test at the factory and leave the blocks in a knowable state of 1 or 0.... something to give a baseline on changes in the drive....  
(Version 1.0)

SMKOL  Nice program, but on intel is alittle unstable. Not sure what triggers it but suddenly the cpus will go 100% and it can't be communicated with - just force quit. How soon to a intel version?  
(Version 1.2)

SMKOL  They're working on an update - 3.0.5! Keep watching - new features and smarter filtering!  
(Version 3.0.3)

SMKOL  I also use privoxy and many of the reasons outlined are still true.

I would add a few comments. First, the released version is PPC only. You can get an Intel version - setup DarwinPorts on the intel and there is a privoxy setup to install - it compiled well on mine and delivered an intel based version of the program. Stop the old version, delete or rename the old main app, copy the new one from under the /opt folder of DarwinPorts to the main installation and then, reset permissions, and start it back up. I haven't noticed a big difference in performance but I felt better ( :-) )

Now, one thing that has bothered me a for a long long time. I'm concerned about nepharious web traffic that virus or trojan-like. At the mild level it's adware which doesn't yet affect the Macs much and at the severe level it's the security updates we get. I thought it would be smart of Privoxy to actually scan incoming content with a formal virus scanner. I see evidence such a thing was actually suggested before the final release with a contribution someone offered - but it's nowhere to be found.

Some other schemes exist to do this, but most aren't Mac friendly, or mature, or easy or require a whole sale reconfig of your entire network, in order to use.

I think such an addition would be a very great thing. Apple's pretty much tossed sand in the faces of virus writters with their recent ad campaign....
