Dear gottwald,
If change your code to:
Dim editor
Set editor = New CuteEditor
editor.ID = "detail"
editor.CustomCulture = "de-de"
editor.EditorOnPaste = "PasteCleanHTML"
editor.BreakElement = "p"
editor.Width = 750
editor.Height = 300
editor.Draw()
Can you test whether it works? You can comment some of your code and then test it, find the exactly line which leads to this issue.
Regards,
Eric
