If you are still using floppies....
No ArahWeave in the menu
You have installed ArahWeave, now you can not find it in the menu.
If you have installed it properly, you should have three new icons on your desktop, ArahDrape, ArahWeave and ArahPaint. To add them to the menu, follow these instruction.
No items on desktop
Starting with OpenSUSE 11.2 the KDE4 desktop is quite different than the old desktop. If you like old fashioned behavior of your Desktop, you can change the settings following these instructions.
The buttons in ArahPaint toolbox are missing
If your ArahPaint window looks like the one on the left, you are missing the KDE style. It is not installed with Opensuse by default, but it is easy to install it afterwords. Just follow these instructions.
