Crashing Question

[Blastenfrog]

It has happened on brand drop down box on the import screen and it has also happened on the drop down box for the bookid on the show screen. Then the hour glass comes up and it freezes. You cannot even control-alt-delete and end the program. You have to turn the computer off to get hoster to work again. Other programs will still work after this freeze without restarting so windows is not freezing. THere is not a particular song or brand it has happened on a number of them.
