Hi Hannes,

You can use latest Cog from http://www.mirandabanda.org/files/Cog/VM/  
. Please use the non MT variants.

If you´re on a Mac (this is for others reading, I see you´re on  
Windows), then using  
http://www.squeakvm.org/mac/release/Squeak%204.2.5beta1U.zip will  
enable the use of graphics clipboard and RTF clipboard with  
StyledTextEditor. This is because this VM includes

>>>    - Deep cleanup in Paragraph and paragraph display services in Canvas

>>>    - More TextMorph cleanup.
>>>    - Numeric enhancements done by nice and jmv, both on Squeak and Cuis..
>>>    - Many minor enhancements, cleanups and bugfixes.
