Newbie: Clicks accepted in some windows and not others

[andrew_hardy@sky.com]

In brief:
Can click on some windows on remote desk top, but not on others.

Detail:
I have the server on my daughters machine and client on mine.

I connect to her machine and see 3 windows/dialogs

1.  Windows Family Safety Login (on top)
2.  Upgrade dialog for AVG (I think)
3.  ZoneAlarm warning dialog.

Also my daughter has a fancy mouse setup.

I have pointer events active.

I can click on the family safety signin dialog and access all its controls,
but I CANNOT select check box and allow button on ZoneAlarm warning
(although the Allow button does change shade as expected when I hover), also
I CANNOT select the AVG update dialog or any of its controls.

Neither of these two windows will come to the foreground even just clicking
on the tite bar.  BUT if I go to my daughters machine it all works fine.

Are some dialogs/windows blocked from VNC or is there some kind of always on
top issue here, or what?

I spent a while searching the archive, but obviously I have the wrong search
string or this is a new problem.

Any advice greatly appreciated.

Andrew
