Thank you for an information. Please don’t understand me wrong, I use Comodo Firewall in a production environment and the sudden lack of this - actually very important - functionality is, simply speaking, not good.
Moreover, what seems even stranger, I’ve just spent more than one hour reverting back to three older versions of Firewall 10, back to the 10.0.1.6258 - and it still doesn’t work, even after uninstalling the newest version and then installing (much) older one. And I did use the Filehippo’s older versions repository.
Can you please comment on how to bypass that lack of sandbox functionality? I know that CCAV Beta already has this implemented, however I don’t use A/V software anymore and don’t want it, just need a combination of a (fully controllable) firewall and a usable sandbox. Anyway, in the meantime, I’ll try to install CCAV Beta alongside the FW 10 and what happens.
EDIT: Installed CCAV Beta alongside the FW 10 and the sandbox works, copy-paste works, but what is not working is the bypass of virtualization to certain folders (which is available and works in FW10).
