Oracle 9.2 on CentOS 4.7 (virtualbox) - strange

[voozeck]

Hi,
I came across the problem in installing Oracle on CentOS 4.7
(virtualbox, RAM 512MB, HD 10GB)

I performed all preparations according to instructions at http://www.puschitz.com/InstallingOracle9i.shtml.
Oracle installer starts but it ignores pressing the button Next, it doesn't react at all.
There are only several messages on terminal from the reason of lack of 'Symbol' font..
Logs *.err and *.out in /tmp/OraInstall.. are empty.

Can you solve the problem or give some hints?
Peter
