cursor pointer select file button not showing

Hi,

I found out there was something weird going on with the cursors of the select file and upload button. The Upload button always had the pointer (hand) cursor, even when there was no file selected. I managed to change this with custom CSS. However, the select file button never shows the pointer cursor but always the arrow typed one. Is it possible to change this? Or should this work fine by default and is there an problem somewhere else that mess-up the cursors?

Thanks! BTW: very nice plugin, simple and does the job!
