To install wine, extract the *.tar.gz wherever it's convienent, anywhere. Usually these 'tarballs' are just source code which you need to compile with './configure; make; su-; make install'. Example:
$tar -xvzf whatever-154.tar.gz
[text flies by]
[more text, the actual compiling is taking place]
[now you swtich to root & the stuff is installed]
The instructions may differ slightly, that's why there is the README or INSTALL file to help you in the whatever-154/ folder. For example, Wine recomends in their README to install with their 'wineinstall' tool instead of 'make'ing & './configure'ing. You probably don't want to compile Wine, it'll take an hour or two. Search for the precompiled binary 'RPM's for Red Hat. They are usually the first in the list
. The RPM packages have dates on them, plus the processor type. All new processors will use i686. I think only the new AMD processors can use 'athlon'. Use the appropriate Red Hat tool to install the RPM. It'll be much faster than compiling.
WineX is a different story. Unless you pay them some $$$ every month, you'll have to compile it yourself.
For your ac3d, how did you install exactly?
The strange menubar is either Karamba or SuperKaramba. You can see the original KDE panel, Kicker, at the top. Look at 'KDE Improvements' at www.kde-look.org
. The bar on the side looks like Gkrellm.
