As of yesterday I now have Sandboxie (Unregistered) on all three of my home PC's. Please answer the following questions: 1. Is the $30 Registration Fee for all PC's in the home or just one PC? It appears to me from Sandboxie's website that the fee is for all PC's in the home. 2. I have set the default sandbox to delete on browser closure. What are some of the easy (for Sandboxie Newbies) tweaks to make Sandboxie more secure? Thank you.
