Why is it necessary with a software cursor? Is it:

1) the need for double cursor (both the dot and the real one)?

and/or

2) to be able to watch the cursor, even when another X11 window has focus=
,=20
eg. without having to move the real X11 cursor?

For 1), i don't want the dot anyway.=20

For 2), wouldn't it be possible to use a software cursor when the viewer
window hasn't focus, but use the real X11 cursor when it has focus? Also,=
=20
this is not a problem in fullscreen mode.=20

This is all nice, but my problem now is that our customers aren't
accepting either flickering cursors or the extra dot. We are currently
forced to patch vncviewer to the 1.2.4-style.=20

Would it be possible to add options for configuring this? I can probably=20
help with writing the code needed.=20
