I recently upgraded from Flex 2.0.1 to 3.2. I have a class that extends
mx:DataGrid. In Flex 3.2, some instances of this grid class are rendered
just fine, but some instances (about half maybe) are drawn incorrectly - the
first row of data values is drawn on top of the column header row. At least,
that's the visual result.

So far I haven't been able to isolate a root-cause or even a good clue to
separate instances that work right from those that don't.

Has anyone else seen something like this?

I've reviewed the issues noted here:

http://learn.adobe.com/wiki/display/Flex/Backwards+Compatibility+Issues
http://butterfliesandbugs.wordpress.com/page/2/

But I don't **think** any of them are related to this issue:

- my flex2 code did not use/override DataGrid.drawHeaderBackground
- I've tried to locate and correct all of the changes for decreasing
rowIndex and rowCount/lockedRowCount by 1

Any suggestions are much appreciated.

Thanks,
- Glenn
