I installed the trial version of Prevx 3, 3.0.5.40(?) on my Windows 7 Pro pc alongside NIS 2010. Also installed is Sandboxie, which co-exists nicely with NIS. But after installing Prevx I can't open FF 3.5.7 sandboxed. FF opens when I didn't sandbox it. Removed Prevx, ccleaned the system and opened FF in Sandboxie with no problem. I don't remember reading anything about this but it has dampened my enthusiasm for Prevx for now. I'll try again in a month or two. Thanks.
I'm unaware of any other user having this issue with Sandboxie/Prevx and Prevx won't integrate with a Sandboxie-protected browser. It might be worth sending a scan log to report@prevxresearch.com to see if we can find any source of the problem. Let me know if you find anything else!
Re-installed Prevx 3 and the same problem exists. I still can't use Sandboxie with P3. I sent the scan log to support. Hopefully they can figure this out. Thanks. Hugger
