Not much of a review, but just a few quick comments.
As you can see:
I have a sandbox for just about everything.
I started using Sandboxie as a trial version.. and whilst it was great, I just really needed the extra features of auto-start apps, and multiple simultaneous sandboxes.
Since Sandboxie as a trial version had never let me down.. I decided to upgrade. Let me say.. Best - choice - ever : ]
This app is s.o.l.i.d. -- it has not crashed or let me down even once -- and I use it for absolutely everything.
Previously, I used to norton ghost my system every 2 to 6 months.. I haven't been using Sandboxie that long yet, but my intention is to depend on ghost far less than previously. And so far its looking great.
Also, Tzuk is very interested in releasing new versions, and always listening to what the users have to say.
I rarely buy an app online, maybe once or twice per year on average.. so the fact that I bought Sandboxie after using the trial, should be significant enough that show I am truly impressed.
