Hi,
To reproduce the bug:
- Go to Tools -> Collection (Under Library)
- Select an existing collection (for my case I selected NICOT & NICNT)
- Detail view (the list disappeared), Icon view (list re-appear)


This bug is very basic, I search the forum, but, cannot fine similar bug report.
I have tested this on my 3 L4 environments, all exhibit the same problem.
- Logos 4.2a Beta 5 (4.21.4.9518) for Mac OS X 10.6.6 and
- Logos 4.2a Beta 5 (4.21.4.9488) for Win XP Pro SP3
- Logos 4.2 SR-2 (4.20.4.8828) for Win 7 x 64bit
Can someone validate, that it is indeed a bug. Thanks.
