There are two different windows that are used for bringing up the on-screen keyboard.
The first window can be placed anywhere on the screen and used for showing and hiding the on-screen keyboard.
The second window is shown as an icon next to the text cursor. If there is no text cursor on the screen, this icon is not shown.
You can change the size of both windows, adjust their transparency and also make them disappear if the keyboard is displayed on the screen.
Auto Hide - hide when the keyboard is visible.
Show the floating On-Screen Keyboard icon next to the text cursor when possible – To open On-Screen Keyboard next to the location where you want to enter text, tap the floating On-Screen Keyboard icon. The icon appears automatically when you rest the mouse pointer or pen near the field that you want to complete, such as the Internet Explorer Address Bar, or when you tap the location on the screen where you want to insert text, for example, in the middle of a paragraph in a Microsoft Office Word 2003 document.
Some applications draw the text cursor in their own way and do not provide information about its position: Firefox, OpenOffice, CorelDRAW etc.
