Last time I used paint in Windows 7 and, boy, was it crippled beyond recognition! Palette management - terrible, tool switching - horrendous, working with 8-bit images - plain impossible (it ruins BMP palette no matter what you do)! The only remaining use for mspaint for me was occasional math/dev schematic sketch. Shame on you, M$!

(no, I didn't move to paint.net. LodePaint, Wally and pure old PS (before CS))
