I am not sure if this is due to the Pulsar OS itself, but you guys may be able to help out

After browsing through any AKAI CDROM in the Pulsar file browser, I can't EJECT the CD from the drive anymore (!). It looks like the Pulsar OS doesn't "let go". The only way I found is to reset the machine (quite annoying when you are in the middle of a project).
It never happened to me prior to installing v3 (which I dearly love), so I thought I'd post here before buying a new CD drive (its a DVD one btw).
Thanks for your help in advance,
Best regards,
