Problems with Yahoo Finance Graph Page

• Component: WebCore JavaScript
• Status: RESOLVED INVALID

When using the compare to other stocks popup on the expanded graph page, comparisons don't work correctly.

Two issues I found, comparison selections don't take and the mouse pointer disappears and flashes on the popup the second time and after the pop-up is accessed.  These could be the same underlying problem.

Steps to reproduce:
Open a page to http://finance.yahoo.com and then select a stock ticker (e.g. AAPL).
Select an expanded graph below the summary graph, e.g. 6m.
Pull up the Compare pop-up window and select another stock ticker, e.g. MSFT and click [Draw]
  - Note that the graph doesn't include the comparison stock.
Pull up the Compare pop-up again and try to select another ticker.
  - Note that the ticker selected the first time doesn't have a check and that the mouse pointer disappears or occasionally flashes.
  - If you can navigate with the hidden mouse pointer, you can select other tickers and clicking [Draw] works.

Note that the page is implemented with the flash pluggin and that Firefox 3.6.10 operates as expected.

We should have separate bugs about flickering and about the second stock not being displayed.

However, I think that neither is a WebKit bug:
- Cursor flickering that I've seen on this widget before was caused by the plug-in actually hiding and displaying the mouse cursor. This was an issue with a script within SWF. It was not readily reproducible - it flickered one day, and didn't next day.
- I can reproduce the issue with Microsoft stock not being drawn in Firefox, too.

Sounds like this is up for Yahoo to resolve (and to switch from Flash to canvas, really).
