I have two screens with the following layout:

                 +--------+
                 |        |
     +-----------+        |
     |           |        |
     |           |        |
     |           |        |
     +-----------+        |
                 |        |
                 +--------+

where the left screen is "primary".

When I use "f.zoom" on a window in the right screen, its vertical size
is changed so that its bottom is at the bottom of the right screen but
its only extends up to the top of the *left* screen instead of the top
of the right screen.


I.e. before:

                 +--------+
                 |        |
     +-----------+        |
     |           |  +--+  |
     |           |  |  |  |
     |           |  +--+  |
     +-----------+        |
                 |        |
                 +--------+

after:

                 +--------+
                 |        |
     +-----------+  +--+  |
     |           |  |  |  |
     |           |  |  |  |
     |           |  |  |  |
     +-----------+  |  |  |
                 |  |  |  |
                 +--+--+--+

Hello,

I just tested using virtualbox and the following setup:

Screen 0: minimum 64 x 64, current 1440 x 600, maximum 32766 x 32766
VGA-0 connected 800x600+640+0 0mm x 0mm
   800x600       60.00*+  60.00*
VGA-1 connected primary 640x480+0+60 0mm x 0mm
   640x480       60.00*

which should match yours, and it works as expected.

Could you recompile with DEBUG macro set to 1, and copy/paste the message printed here:
https://github.com/fullermd/ctwm-mirror/blob/master/ctwm_main.c#L459-L462

For the above setup it prints:

Layout: [monitors=[len=2 cap=2 [x=0 y=60 w=640 h=480] [x=640 y=0 w=800 h=600]] horiz=[len=3 cap=3 [x=0 y=60 w=1440 h=480] [x=640 y=0 w=800 h=60] [x=640 y=540 w=800 h=60]]
 vert=[len=2 cap=2 [x=640 y=0 w=800 h=600] [x=0 y=60 w=640 h=480]]]

Do you use Xrandr rotation for HDMI-1? I didn't succeed to test monitor rotation using virtualbox...

Max.
