ACE is a compression format. Although it is not recognized by KDE, there is a command line utility (unace) to decompress them:
unace -e filename.ace
I have been using several trial versions (2.0.1 and 2.0.2) of Crossover Office. Actually it doesn't do really much. Admittedly, it really has some handy functions: "Reset Crossover Office" to terminate any stuck wine applications and "Simulate Windows Reboot". These are actually scripts (located in /opt/cxoffice/bin), that could be largely replaced by own solutions.
Finally I figured out where to set the time sync option in Suse 9. Unlike RedHat Suse doesn't ask you during installation whether and which public time server to use:
Control Center -> YAST2 modules -> Network Service -> NTP client -> Authenticate as administrator -> Delete the CMOS entry -> Add
Type the address of a public time server. I used this time fartein.ifi.uio.no, but there is a long list with server to choose from at http://support.ntp.org/bin/view/Servers/WebHome.
