Many thanks to all of you for your answers.
@marcov: I use the last version of ReactOS. And, yes, I will file a bug.
@SkyKhan: IMHO, the stability of Windows ME crucially relied on the stability of the applications using it

@Ñuño_Martínez: I agree with you.
@Paul Breneman: Thanks for your links. I'll report back if I find something interesting.
