Changeset 21885 for branches/gcc-kmk/include/winkeyboard.h

Timestamp:

Message:

Fix crashes in GUI apps when pressing modifier keys.

This was due the fact that BYTE is signed in the toolkit and converting it
to an unsigned int causes the sign bit to be extended in the result while
the code assumes that the extension is made with zeroes (this is how
VAC converts signed integers of smaller precisions to unsigned ones).
