Wow! I had the similar issue. My pc hangs whenever I tried to turn on pipboy light (hold tab) during conversation. Tried to reinstall FO3 with just DLCs (no mod except unoff patches), but no success. It kept hang until I tried your solution, it worked!!! No more hangs for now. Kinda strange since Point Lookout is an official DLC, I thought it shouldn't have any problem with any other DLCs. Here's my current working load order: Fallout3.esm Anchorage.esm ThePitt.esm BrokenSteel.esm Zeta.esm PointLookout.esm Unofficial Fallout 3 Patch.esm Unofficial Fallout 3 Patch - Operation Anchorage.esp Unofficial Fallout 3 Patch - The Pitt.esp Unofficial Fallout 3 Patch - Broken Steel.esp Unofficial Fallout 3 Patch - Mothership Zeta.esp Unofficial Fallout 3 Patch - Point Lookout.esp Total active plugins: 12 Total plugins: 13 There's FakePatch_v1.5.0.22c.ESM but i'm not sure whether to turn it on or not, since I was using Better Oblivion Sorting Software and it doesn't recognize the file. Anyone has idea or experience about this? I'll install FWE, FOOK2 v1.0 (since 1.1 has yet compatibility issue with FWE), MMM RC5, WMK, and Project Beauty soon. Hopefully everything's gonna be ok. Oh, I'm running Vista with 1.7 FO3 patch :)
