GW blocks some "Active" (allowed) apps

Notwithstanding having been allowed (“Ask To Connect”) some apps, listed “Active” on the Firewall, are blocked. Setting Firewall to “Click to Block” lets them through. Starting this AM it occured for the first time with Thunderbird and Speedtest, previously occurred with Flashget. There have also been periods of days where everything worked properly.
Solution?
Update: uninstalling GW then re-installing with the latest version 2.2.291 seems to have fixed the issue. Crossed fingers.

Sorry for the issue. If it comes up again I have made this helpful guide.
