Swing1.0:
In the example below: please insert a Component somewhere in the text with one of the buttons.
Then select a range that contains the component, cut it (ctrl-C) and paste it somewhere in the text:
Only the cutted text without the control is pasted, with a single space instead of the control in it.

Example code: - borrowed from another bug, please _ignore_ the meaning of the text inside the textarea.
