Using latest JS from jquery and UI in FF :
On my UI there are 4 sets of H3+DIV elements stacked vertically within a jquery ui resizer DIV. On initial load one of my DIV's has 60+rows of data loaded from an ajax call. If i click the H3 heading for that div initially, the UI will open the drawer and show all the data well down below the limits of the resizer DIV, and the page... there are no scroll bars, just lots of data.
O page reload, If i resize the resizer DIV first (not the window), THEN click the H3 header, scroll bars appear and the data sits nicely within the div boundaries. Keep thinking some combination of autoHeight, fillSpace and clearStyle will fix this but have run out of ideas.
