Web Player failing to receive inputs after changing tabs

Hi,

We've observed that the Unity plug-in fails to receive inputs properly after changing tabs in Chrome and Firefox in one of our computers. It seems to work ok in Explorer. The machine is a laptop, so not particularly powerful.

It's not happening in other machines though. Do you know if this may be due to a bug in the Unity plug-in or something related to our own code? Do you know if it's related to a known bug by any chance and/or if there is any known solution?

Thanks,

Eduardo
