format problem on text insertion in Word 2000

[Edwin Herrmann]

Hello,

STEPS:
1) I delete from "HelloWorld<Space><Crlf>" the part "HelloWorld".
2) I insert a formatted text like "NewText" (bold or underlined or
whatever)
=> "NewText<Space><Crlf>"

PROBLEM:
Word automatically takes over the format of "NewText" to <Space><Crlf>
=> EVERYTHING is now formatted instead of just "NewText".

Does anyone know how to switch this annoying word behaviour off? I use
this in VBA and this behaviour results in errors.

Thanks in advance!
