Cakewalk 7.0 uses a different mouse cursor draw technique. It's probably just a matter of time before screen reader software catches up. Meanwhile, to revert to the
Cakewalk 6.0x cursor draw method you'll need to edit your CAKEWALK.INI file. Open it with a text editor (like Notepad) and add the RectangleHiLite line as shown
below:

[Wincake]
RectangleHiLite=1

The Default setting is 0. If set to zero or omitted, Cakewalk 7.0 will use the new draw technique.
