I'm not looking for the ones that know about terriers, rottweilers, golden retrievers or poodles. I know "there ain't nothing but a houndguru..." but I need a Browser (not bowser) guru. [Woof, woof, growl.] Sorry Wave :) But, seriously... I change the column width of my single column data browser when the window is resized or a container is opened and this works well. But, I'm having problems when the container is closed. I call my width change function from "ItemNotificationCallback", _kDataBrowserContainerOpened but, it seems, _kDataBrowserContainerClosed is triggered _before_ the container is closed, not after. So, calling my function from here doesn't do anything because, at that time, the container still appears to be open. Any clues? Bernie
