Stopping the User from Adding/Removing Lines to a field

[valetia at mac.com]

Hi Igor,

To prevent people from pasting multiple lines of text, you can:

1. Trap it via the 'pasteKey' message; and then

2. Use the 'clipboardData' property to help you allow only the first line of
whatever's in the clipboard to be pasted into the current selection.

Hope this helps.

Valetia :-)
