hi all, agnitum has published sp2 related advisory for outpost 2,1 users. "1. Right click on My Computer icon and select Properties. 2. Go to Advanced, press Settings buttons in the Performance section. 3. Go to Data Execution Prevention and check if you have DEP turned on for all programs, not only system applications. If yes, then press “Add”, go to Program Files, open Outpost folder and move Outpost to the exclusion list. 4. Restart your PC. By doing this, you exclude Outpost from the list of applications that are partially blocked by DEP and thus prevent system dysfunctions." this applies to any firewall, actually, as logn as i understand, so it might be useful for anyone. there is some more info on http://www.agnitum.com/support/sp2.html .
