mozilla on Linux 9.1 did not accept keyboard input when I used my
usual windowmanager. I traced the problem to libgdk -- it requires
that focus be bound to a specific window instead of following the
pointer -- and in the message quoted below you said it would be fixed
in 9.2.
Mozilla on Athena 9.2 Linux works properly. Mozilla on Athena 9.2
Solaris does not accept keyboard input. According to ldd and pldd,
mozilla-bin is using a libgtk found in /usr/sfw/lib rather than the
version in /usr/athena/lib. (If I use LD_LIBRARY_PATH to load the
athena gtk/gdk mozilla displays nothing at all or crashes. mozilla
was probably linked against the /usr/sfw library and the /usr/athena
version is not compatible.)
You can patch /usr/sfw/lib/libgdk-1.2.so.0 with adb to fix the bug
(two missing bits in a lookup table):
gdk_event_mask_table+34?X
gdk_event_mask_table+0x34: 200000
?W 200030
gdk_event_mask_table+0x34: 0x200000 = 0x200030
(I just tested this.)
