Many apps released as Windows portables and dual 32/64-bit installers

In recent days I have released the following applications:
A-880 Manager 3.1.0
BCN44 Manager 1.4.0 Alpha 1
CSV Doctor 1.4.0 Alpha 1
D-5 Manager 2.0.0 Alpha 1
FCB1010 Manager 2.1.0
MIDI Tools 2.1.0
ProMix 01 Manager 1.4.0 Alpha 1
R-8 Manager 1.5.0 Alpha 1
XG Manager 1.5.0 Alpha 1

Several GUI-related bugs in OS X applications fixed

New versions of several applications are now available for OS X:

A-880 Manager
BC Manager
MIDI Tools

Most significantly, the new version of BC Manager fixes a window-related bug that often produced "Division by zero" error boxes on application termination.

Additionally, all these versions improve the behavior of the menu bar.
