Question RE Google Docs on N900

I can open stuff, edit stuff etc etc all fine, but the problem is I can't scroll the box. And in the spreadsheet page I can't move around the sheet using the arrow keys.

Are these known limitations of the Micro browser or is there a magic setting somewhere that "enables" such things...

I don't think anyone else has reported these issues so I guess its to do with my setup rather than an inherent incompatibility.

Thanks for any advice
