There has been some discussion on various apple fora about Safari 3.0.4 randomly dropping people's cookies, but I've not experienced this myself. then again I haven't yet gone up to 10.5, which seems to be part of the problem...
hmmm... this says the problem occurs when a server sends "a completely absurd cookie value" to the browser, which safari barfs on hard enough to lose all it's saved cookies... does the package installer set some particularly long or strange cookie?
