[TYPO3-english] Problems staying logged in with two installs on same site

[Tomas Mrozek]

I haven't noticed that when I was doing update 2 days ago.
Now I tried it and indeed I'm getting logged out. That's a real bummer 
if there's no workaround for this. My joy caused by one bug getting 
fixed in 4.2.4 seems to be now over.
