mapakunk,
I also had been looking for this solution and am thrilled to have stumbled onto your posting. The only problem I still have is that the font does not transfer to excel. The size, color, and italics transfers but the actual font remains Tahoma. The font does change for the other window tool tips. Any ideas how I can change the font default for comments? Also it would be nice if I could set the default for auto-size as well.
Thanks,
