I think I have finally discovered why by playing with the group settings to try and force it.
the flash video gets its name from the parent (checked using sleep5 && xwininfo <-- needed sleep so I could click the fullscreen button)
adding these should force fullscreen
<Group>
<Class>seamonkey-bin</Class>
<Name>seamonkey-bin</Name>
<Option>pignore</Option>
<Option>hmax</Option>
<Option>vmax</Option>
<Option>maximized</Option>
</Group>
the maximized tag works as normal for seamonkey-bin as long as hmax or vmax is not in place, however adding them PREVENTS instead of forcing maximization
it appears that flash10 just uses maximize while flash9 uses HMAX and VMAX
flash9 is still being updated and is 2MB smaller with less dependencies so it would be nice to get this fixed ... who knows what other issues it will fix along the way - I think there was a related gxine bug too
Hopefully someone can confirm - I could be completely off base because I have zero C skills... anyone???
EDIT --- further info
from joewing.net documentation
hmax Make windows in this group maximize horizontally by default.
vmax Make windows in this group maximize vertically by default.
hmax expected - window opens maximized horizontally
hmax actual - window opens as normal when maximize is press it ONLY maximizes horizontally
hmax & vmax expected - window opens maximized horizontally and vertically
hmax & vmax actual - window opens as normal when maximize is press it does not maximize at all
it seems like jwm is setting the window state as maximized (V or H) instead of performing the action
for instance in hint.h there is
- ATOM_NET_WM_ACTION_MAXIMIZE_HORZ,
ATOM_NET_WM_ACTION_MAXIMIZE_VERT,
- ATOM_NET_WM_STATE_MAXIMIZED_VERT,
ATOM_NET_WM_STATE_MAXIMIZED_HORZ,
