I reported a memory error that was generated when I tried to enable cookie protection on Firefox and SeaMonkey a few years ago on Spywareblaster 3.5 or so. I upgraded the computer from Windows 2000 to XP and now on SP3 and just installed Spywareblaster 4.6. I have had that problem thru all those versions. It may have been caused by the problem with Spybot many years ago but I have uninstalled and reinstalled both programs and the problem has never gone away. I check in here now and then to see if there has been a solution but I don't see one yet.
