Details:
As noted in the source comments the X state flags are updated after a key
press/release, and as such they cannot be relied upon to indicate the correct
Openstep modifier state (as the modifier changes). However despite this, the
code does depend upon the X state for the shift keys.
As such, a shift press results in flagsChanged: being invoked with the
NSShiftKeyMask bit clear, and a shift release in an invocation with the bit
set.
The fix is obvious, namely to treat the shift modifier in the same manner as
the other modifers (control/command/alternate).
Suggested diffs are attached, along with a program which demonstrates the
issue.
