Hi Fred, Uday, I've done some digging and I can now always reproduce the problem. I don't think it has anything to do with logging on to BBO. A screengrab of the offending buttons: http://xs.to/xs.php?h=xs136&d=09063&f=bbo_vg_buttons573.png My Environment: Firefox: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.6) Gecko/2009011913 Firefox/3.0.6 - Note that I did this yesterday on the previous version with the same result Adobe flash player 10 Repro steps: In firefox I load: http://www.bridgebase.com/client/vugraph.php - loads fine I then resize the right container using the vertical separator to be about 75% of its original size. The right container holds the results table and the table image. I then reload the page. On reload, I see that - The container is now back to its original size - The buttons as shown in the image above are there The buttons disappear when I force a refresh such as resizing the right container or doing some other things. I was not able to reproduce this on IE(8) or Safari. I'm not sure if their flash plugins is different, or perhaps they are executing the refresh code that hides the buttons, while firefox doesn't execute it. The vertical dimension of the browser window doesn't seem to matter. Originally I though it was linked to the logging in to BBO, since I didn't see why the Who's online and My Results buttons would exist in Vugraph, but now I think they are in your Viewgraph app itself. Which leads me to wonder if this is even the right viewgraph app, I may have found it via google, so perhaps it's an old version? To answer your question of what did I mean by logging in, I would log in to BBO in one tab, and then open that viewgraph page in another. Always in firefox as described above. Clearing the flash cache (setting local storage to 0, I think should do that) did not have any impact, the behavior persists. The buttons are not able to get my mouse clicks, clicking them just passes the click down to the tabs below, and the tabs below have a highlight effect while the buttons themselves do not change at all. If you'd like me to assist in helping you reproduce the problem, or have any other questions, please let me know. Many thanks, Tom
