Open 1 window for each engine and reuse that window for that engine (Default)

Then, if you again perform a search, this time selecting Yahoo and Excite, the results for Yahoo will be shown in its original window (i.e. its window will be reused); the Altavista window will remain unchanged; and a new window will be opened for Excite.

Tip: This option allows you to perform multiple searches simultaneously.

Use only 1 window for my searches and keep reusing the same window for all engines

Tip: Use this option to conserve your system resources by opening fewer windows.

Keep opening new windows for each search and not reuse any existing windows

Tip: This option allows you to perform multiple searches simultaneously and also retain your past search results.

Warning: This option can use a lot of your system resources by opening several windows.

Note: The Close selected windows button will close only the last window opened using this option.
