simplewall and Windows Firewall works different.
- Windows Firewall have low-level driver callback which freeze connection until you are decide what you do with him (allow/block).
- simplewall have user-mode level and no drivers installs and cannot freeze connections for wait your decision.
Thats why simplewall do not remove notifications cache.
New version comes with some patches on this logic, but notifications still on cache until you do not do anythig with blocked application.
Are "Allow listen connections for all" is checked? "Stealth mode" enabled? You see logs? Whats applicaions blocked? Do you checked this apps?
In near future i will pass some tests with Windows Store and create "System rule" which allows it to working.
