The Appearance properties page allows you to select amongst several options.
Remember Last Window Position
If the "Remember Last Window Position" item is not checked, the program window will always open in the center of the screen. If the "Remember Last Window Position" item is checked, the program window will open at the same location on the screen as when the program was exited.
Exit on <Esc>
If the "Exit on <Esc>" item is checked and the main program window is active and on top, the program will exit when the Escape key is pressed.
Allow Multiple Instances
If the "Allow Multiple Instances" item is not checked, only one instance of Converber can be open at a time. During an attempt to run Converber with the program already running, the running instance will be activated. If the "Allow Multiple Instances" item is checked, more than one instance of Converber can be opened.
Use multiple user named preference files
After running the program the first time a preferences file is created to store such information as the last used units, last used category, last used input value, window position, favorites, history, significant digits selected, decimal-point precision, scientific notation setting, update settings, help file preference, selected language file, list of enabled and disabled conversion equation files, show all/common files selection, transparency setting, and last selected units within each category. This file is titled "Preferences.ini", by default. This is ideal for USB Drives and the like. Alternatively, multiple preferences file can be selected, titled "{user_name} Preferences.ini".
If the checkbox is disabled or greyed out, the installation directory is read-only (such as Windows Vista, Windows 7 and Windows 8). In this case, the user's application directory is being used to remember the options/preferences. Since the user's profile directory is being used, this option is no longer applicable.
Use online help
A help file(Converber.chm) typically exists in the working directory if selected during installation or manually copied to the working directory from the zip file(converber.zip). To save disk space, or to use help in a language other than English, an option has been added to use online help. With "Use online help" selected, the user will be taken to the appropriate web page via the default web browser.
If the checkbox is checked and greyed out, the help file was not installed and the default browser will open the website when a help button is pressed.
Transparency
The Transparency box alters the transparency of the main window. A transparent object is viewed by light shining through it from behind. This allows the desktop or other software to be seen under the active window. Any level of transparency is available from fully transparent (0%) to non-transparent (100%). Transparency is only available in Windows 2000, XP, 2003, and Vista.
Language
The Language box allows users to select a different language. A View button is located directly beside this box to provide quick read/write access to the selected language file using the default notepad editor. For more information on the language file, please go here.
Calculator Path
The Calculator Path box allows users provide a path to their favorite calculator application. Relative paths are supported. A relative path is a path relative to Converber's working directory, so the full absolute path need not be given. For instance, if calculator.exe is in the same directory as converber.exe, 'calculator.exe' is all that needs to be entered in the box (ignore the single quotes). To move up a directory use '..\'. To move up two directories, use '..\..\'. By default, Windows calculator '%calc.exe%' is used.
