WebPositive Settings - search parameter sometimes interpreted as literal

[IIsi50MHz]

WebPositive allows setting a default search page with the parameter "%s" used to represent a user query. When no query is provided, the parameter is incorrectly interpretted as a literal. This seems not specific to a particular search provider.

Example:

1. Launch WebPositive and select Windows > Settings from the menubar.
2. Set the "Search page" setting to: ​https://www.google.com/search?q=%s
3. Set the "New tabs" setting to "Open search page".
4. Click the Apply button and close the Settings window.
5. Peform a search in the addressbar; results appear as expected.
6. Open a new tab; an unexpected search for "%s" is performed.
