Hi, I need some advice from you. Currently I'm still using the "old version" Sandboxie 3.76, that works wonderfully on my system with windows7-Pro 64bit-SP1, but now I'm undecided if to upgrade to version 4 or not!??!.... In fact, I remember that the first releases of version 4 had some bugs, and many users had issues and malfunctions. So now I need to know three very important things for me: 1) Are fixed the initial problems of Sandboxie vers.4?? 2) It's advantageous to upgrade to vers.4? ....the version 4 is more secure than ver.3.76? 3) Eventually, which release is better: the latest release of his developer Tzuk (4.08 ) or the latest release by Invincea (4.14)?? Thanks in advance to anyone who will give me advice and..... Happy New Year to all!!!
