It's not in the 1541 release, as far as I can tell. I assume it will show
up sometime.
Here's another bug for you, while we're at it: TwinView doesn't properly
update the display dimensions and DPI when it is enabled. Thus, on my
side-to-side system the display dimensions are set to the *left* monitor
(only) which, when scaled to the screen size in pixels of the *entire*
display area (right and left) yields a grossly inaccurate calculated
x-axis DPI. This is then visible through X to applications (such as
netscape and ghostview) which select grossly inappropriate font sizes
(netscape) or scale everything twice as wide in the x-dimension
(ghostview). The workaround is to set the 'DisplaySize' parameter in the
'Monitor' section to (in my case) twice as wide in the x dimension as the
monitor actually is. TwinView should really handle this itself.
