V126.96.36.19912 (Firewall only) Windows 7 Ultimate 64-bit (clean install with all MS-updates)
When entering a search input in the search field by clicking on the magnifying glass in the “Application” bar in the FW “Application Rules” window and then double clicking on a search-matching FW rule to start to edit the FW rule and then pressing OK (with or without making changes to the FW rule) to close the FW “Application Rule” edit window and to return to the FW “Application Rules” window then the entered search input in the search field is no longer active (the entered search input and search field however are both still visible in the “Application” bar) and all FW rules are listed again without being filtered by the visible search input in the search field.
This only happens after clicking on OK in the FW “Application Rule” edit window, when pressing Cancel the search input and search field are still active and the listed FW rules are still filtered by the matching search input.
In order to filter the FW rule again after pressing OK in the FW “Application Rule” edit window one has to reenter the search input in the already visible search input field.
The above does not happen, for instance, when editing a HIPS rule.
