It has been a while since last time I worked in Buster Sandbox Analyzer (BSA). I stopped development mainly for two reasons: One was BSA was already including every feature I could think of and nobody was requesting new features. The other one was Sandboxie had problems when LOG_API was being injected. I didn't remember exactly what problems were that but I've been digging in the old Sandboxie forum and found this: https://www.sandboxie.com/old-forums/viewtopic1185.html?f=22&t=6557&start=915 "I have news about LOG_API64 problems. After talking with the guy coding the dll and doing some tests we found Sandboxie version 4 (even version 4.10 RC) still has bugs in the dll injection mechanism. Injection mechanism works fine until version 3.76, but since version 4, even after the bug fixes done by Invincea team, is buggy. When LOG_API64 hooks NTDLL/Kernel32 dlls in version 4 the problems appears. These problems are not present in Sandboxie 3.76." https://www.sandboxie.com/old-forums/viewtopica5db.html?f=22&t=6557&start=930 "The problem in notepad SaveAs appears to be a bug in duser.dll. It is complaining of reentrancy. It is very low priority because all it does is cause an error msg to be displayed by Sbie. Notepad keeps running. And how many people are going to be testing notepad under BSA anyway?" After a while, without any replies, I didn't follow up those issues and actually I don't know if they ever were fixed or not. Is anonye still using BSA with Sandboxie 5.x line? Any problems so far?
