WINE programs never crashed running 5 hours.
OpenSuse 11.4 Milestone 5 will boot from YAST with all XFCE, LXDE, KDE, and Gnome installed. FXCE won't show up even though programs will. Expect it to freeze up when memory gets exceeded (with 512 MB of RAM), and if you have 768 MB or 1 GB of RAM than you have no worries. The crashing is 100% RAM related. Wants to go into "Fast boot" than its slow boot fail-safe kicks in after 20 seconds.
To avoid crashing, I looked up "Resolution" in KDE menu search-box and used KDM to change the resolution to 1280x768 with those PCs on 512 MB of RAM. This crash phenomenon is known to happen in KDE 4.4.4 in OpenSuse 11.3
KDE 4.6 beta 2 looks cool by itself. No more kernel lock to increase performance by 10%! LXDE stilll a great desktop shell, and didn't crash. Best for 512 MB of RAM PCs.
Gnome 2.32.2 never crashed yet. LibreOffice looks and acts like OpenOffice. no complaints. Had to install VLC to play audio codec.
