Export audio mixdown window don't work?

Hi

I’ve noticed that when I export a project mixdown,the export audio mixdown window doesn’t work.I mean it remains at 0% and static but after some minutes the audio seems to be exported correctly.

Could it be my old NVidia Geforce 8400GS video card? or some settings that I must enable?
(I’m using old video drivers 335.23 for stability btw)

No big deal but I’m curious about this issue.

TIA

This comes up fairly regularly.

Here’s a fairly recent thread for example …the last poster seems to think changing their Nvidia driver fixed it.
