I just imported nine CD tracks in a row into the playlist while Hoster 3.321 was playing. I even messed with the program trying to move songs on the playlist while it was playing/importing. I could not recreate the "import three CD tracks and 3.321 crashes" bug that is being reported here.
Hoster did not crash.
I'm running a Dell Desktop Pent4 3.0GHz with 512 megs of ram using a stock Dell CD (not DVD) burnner.
I hope this helps.
