I've been running version 4 for quite some time and update to the interim releases to test prior to rolling out to our enterprise. With the last two interim releases beyond 4.0.437 which would include the current release of 4.0.474, my system blue screens with eamon.sys as the culprit. It doesn't happen immediately but within a few days... BSOD. I go back to 4.0.437 and all is good. I'm running XP SP3 as are most of our systems. I can't very well continue the upgrade process to the rest of the Company until I get this solved. Has anyone else experienced this? Thanks for any input.
