[MacTUG] Spaces - popup alert/attention dialog windows how to find them?

[Glenn Anderson]

I am going to try my best to describe this problem.

I have a user of spaces that has noticed a problem. At times an  
application or action causes an alert/attention (not sure of the  
correct Apple term) dialog window.

One problem/issue is that this dialog window doesn't open in the  
current spaces window that he is using, but in one of the other spaces  
windows.

The second problem, and it is more of a problem, is that when he looks  
at the spaces overview window (the one showing all screens) the dialog  
window for some reason doesn't appear.
So he is required to toggle through all the windows looking for it.

Has any one encountered this? If so any solutions?
