Is this a reported issue or not.
VS IDE do not release the lock to the image file. I am creating a skin
file with Photoshop, i saved the file as filename.bmp, set this
background of my form. when i tried to overrite the file. It says that
it was locked by another application. Even if i cliked Clear under
import resource dialog, still i cannot overrite the file. I ended up
with multiple filenames or worst close the IDE to release the lock.
thanks in advance!

If you use Image.Load, the file is locked until you dispose of the image. I'd say the issue is with resource management in your code, and not a bug.
