inhibt windows explorer from closing when SD card removed

no matter what I configure in Autoplay ...
- whenever I say "safely remove mass storage" (in my case it's a SD Card) the explorer window is closed
- it only stays open when I select another drive before "safe removal"
- it also stays open when I just pull the SD Card (unsafe remove)

the drive itself is a combined mass storage reader built into the Desktop PC and ist drive letters are always shown in the explorer

Is there a regkey to tell Windows to just let it open ?

In its infinite wisdom Windows assumes the user is finished using File Explorer [renamed from Windows Explorer in Win7] and to save resources closes that window. It really doesn't bother me as I usually have two or more instances of File Explorer running anyway [for access to External USB HDDs].
