In Sophie I guess you used the extended clipboard exclusively, but for Squeak it's not quite as clear-cut ...

Hi Bert,
I installed Etoys 4.1 on my Mac mini with Mac OS X 10.5.8. I was neither
able to copy nor paste RTF from to Etoys. I tried both with AbiWord and
TextEdit, and all I get is a String (without font styles, alignment or
color). I also tried to paste a graphic (created with the Grab app) and
I also failed (I get the previous String clipboard).
In the first case, ExtendedClipboardInterface current
readAvailableFormats answered an OrderedCollection(text/rtf
text/utf8-unicode text/plain text/unicode), in the second case it
answered an OrderedCollection(image/tiff).
Besides, #readRTFClipboardData and #readTIFFClipboardData have no senders.
What am I doing wrong?
Thanks,
Juan Vuletich
