Julien Ellie, you rock. In response to all the WinForms hubub yesterday, I asked for a higher limit on the file selection dialog (you can only select about 200 ATM). Julien said in my comments:
Well, I see that a KB article (820631) says this behavior is by design so I don't know how much freedom we have here. You'll understand that I can't promise anything, I am just a dev, but I'll make sure to look into it and ask questions about this. Thanks!
That is so slick. Julien, you may be just a dev, but that my friend is the correct attitude to have about it.
In the meantime, the only workaround I've found is enabling drag n drop onto a listbox for file selection from explorer.
