Running Sandboxed Multiple .mp3 Files Using WMP 11

[noway]

If I open a folder containing multiple .mp3 files and select (hightlight) more than one and then Run Sandboxed, instead of playing the multiple files immediately, both "Move Items" and "Copy Items" dialog windows appear. After cancelling these prompts, the files play.

Hi noway.

I was not able to reproduce this behavior. I used the same set up as described above (except XPSP3). When I selected multiple .mp3's and then chose Run Sandboxed, no Move Items or Copy Items dialog window appeared. Instead, WMP11 opened as expected. The only oddity is that only one of the multiple/highlighted .mp3 files appeared in the WMP11 playlist and played.

Have you applied any other non-default settings in the target sandbox (other than Forced Program)?
