Hi, for my 2 pence, I am using XP/IE6 and I just paste from MS Word into the design editor using good old ctrl-v without problems however ....
It is ill advised to edit the resulting HTML either using the Auctiva design editor or the text editor. Corruption can occur and frequently did. Re-edit the Word version delete the entire previous pasting and paste the complete new text.
When I do the paste the Auctiva editor does query about clean up and I always press cancel and in goes the 'unclean' text. It produces some horrific looking HTML. So far no buyers have flagged any problems with my listings and I have posted well over 200 this way.
