Windows 7 - 7-zip and foobar2000

Hi

I'm using the latest versions of the above software.

Let's say I have a rar file with some flac files in it. I open the rar and double-click on a flac file in 7-zip window to play with foobar. Fine. But then when I try to play another flac in that rar in the same way, foobar would give me this error:

Could not update tags (Object not found) on:
"...\AppData\Local\Temp\<temp folder by 7z>\<name of second flac file>"

There is a temp folder created with the first flac file, but not for the 2nd file.

I have to close foobar and reopen the second flac from 7z window to play it.

I don't have this problem with WinRAR. And I don't remember it happening on XP either.

Does anyone have any idea what's causing this? Thanks.
