CR added to LF in clipboard

[miffed]

My clipboard has some lines that end with CRLF and some that end with only LF, but when I paste them into a text document in SlickEdit, all lines end with CRLF.

Is there any way to prevent SlickEdit from adding the extra CR?

(For clarity, if I view the text in Hex, all lines end with \x0D0A, but some should end with only \x0A.)

Thanks.
