I've come across two different behaviors, which both end up in not being able to to the web browser. Web browser: Chromium Sandboxie: Latest beta version SOL: Maximum settings for both https and http Steps (Steps 1 and 2 made separately): 1. Run a non-sandboxed browser session. Everything works great. Close session. 2. Run a sandboxed browser session. Everything works great. Close sandbox. 3. Run a non-sandboxed browser session, then open a sandboxed browser session. Try to navigate to any website. It should not happen anything. The mentioned steps were done, via Chromium started as a forced program. If I remove Chromium (chrome.exe) as a forced program, and then perform the step 3, Sandboxie won't even be able to execute Chromium. Could you see if anything could be done to solve this? I haven't tried to lower SOL settings; but, lowering SOL settings can't be the answer to each and every problem, unless nothing else can truly solve it.
