Just one computer crashes NAV (it just disappears) every time you go to the job list (<company name>/Home/Jobs/Jobs or N050 Job List-Advanced (11014549) -- yes, we have ToIncrease installed ). I uninstalled NAV, stripped out every registry entry, every appdata entry and deleted all C:\Programs* NAV folders that remained. I even uninstalled MS Office for good measure (tried it with and without). Then I reinstalled and tried logging in with different users on that box too. Oddly, it works fine on test but not on our production instance. Any ideas?
