The address bar is not kept permanently visible in order to maximize display real estate. To directly enter an address click the  button, or select the menu option "File" | "Go to a Web Page..." (keyboard shortcut: Ctrl+W).

To open a local disk file click the  button or select the menu option "File | "Open a local file..." (keyboard shortcut: Ctrl+O).

You can also enter a fully qualified file URL (but not just a file name) in the "Open URL" box.

The address of the current page is shown on the status bar at the bottom (except when the mouse is over a hyperlink or while a new page is pending).

To copy the current page address to the clipboard, right-click the mouse on the page and select "Copy Page URL".

Select "Start & Home page" in the Options menu to display the Default Pages dialog, then specify the fully qualified URL address for the Start page, which will be automatically displayed when the browser is started.

Leave the Start Page blank (or use the Blank button) to start with a blank page.

Select "Start & Home page" in the Options menu to display the Default Pages dialog, then specify the fully qualified URL address for the Home page, which will be loaded when the Home button on the toolbar is pressed.

The outgoing User-Agent HTTP header identifies the browser to the server. By default, the Off By One browser uses the identification string "Mozilla/3.0 (compatible; OffByOne; &sys) Webster Pro V3.2". Some rude web sites refuse to serve pre-4.0 browsers, but you can often convince these to communicate with the Off By One browser by using a different User-Agent identification string.

Until a better UI is implemented, you can specify a value for the outgoing User-Agent HTTP header by directly editing the initialization file OB1.INI, which is typically placed in the C:\WINDOWS directory after the first time you run the browser.

This is a simple text file consisting of [section headers in square brackets] followed by lines with Name=Value pairs.

You can use Notepad or any other text editor to add or edit one line to set the name UserAgent to the value of your choice. For example, to look like a 4.7 client, use:

[Properties]
UserAgent=Mozilla/4.7 (compatible; OffByOne; &sys)

A &sys specification is replaced with the name of the operating system when used in the User-Agent header.

This setting will take effect the next time you run the browser.

You can set the default variable width font face and point size. These are specified by the FontNormalFace and FontNormalSize properties, respectively. Follow the OB1.INI editing procedure as for UserAgent in answer #4 above to set these properties, for example:

[Properties]
FontNormalFace=Arial
FontNormalSize=10

This setting will take effect the next time you run the browser.

You can launch the browser with a URL as the command line argument from a batch file, as a shortcut etc. This will run the browser and immediately navigate to the specified URL, ignoring any start page setting.

Be sure to specify a fully qualified URL for the command line argument, for example:

C:\InstallationFolder\OB1.EXE http://offbyone.com

The page cache and image cache are memory-resident and utilize no disk storage, so they disappear without a trace at the end of a browsing session.

Persistent HTTP cookies are stored across sessions in the file HPSW.CKI, which may be safely deleted between sessions for maximum privacy.

A fully qualified URL is a web address starting with a scheme (e.g. http: or file:). For example, here are some fully qualified web URLs:

• http://www.yahoo.com

• http://www.offbyone.com/ob1_help.htm

Here is a fully qualified file URL:

• file:///C:/somefolder/somefile.htm
