I use a color theme with a very dark background, which works great except that VS2010 uses the default insertion point mouse cursor when the mouse is over the editor pane, and t
You can change the cursor, so you don't mess up the theme you want in Windows.
I made two I Beams that I made available in a github project:
DarkThemeBeam
Use those, if you want.
I hope that's easier and less invasive on your eyes than changing the larger desired theme you want to work in.
