I have been running Defensewall and Sandboxie together for some time now for day to day browsing. Both seem to run very well together the only problem i have come across is when i try and open a PDF file in the browser (Firefox) i always get Sandboxie errors "SBIE2399 service RPCSS fails with error 1066. Last checkpoint was 1". and SBIE2399 service RpcEptMapper fails with error 1066. Last checkpoint was 1" Now i think this is to do with Defensewalls resource protection preventing the pdf from loading. It works fine when using DW or SB on there own. Does anyone have a work around for this who uses this combo together?
