sometimes word/excel (maybe other office apps) crashes and only wants to open in safe mode
The reason is that the "normal" template is corrupt.
to fix this you need to rename the normal.dot file since it is corrupt and useless.
it is located in C:\documents and settings\*username*\application data\microsoft\templates
just rename it to something like normal.old and windows will replace add a nice shiny new normal.dot file and word/excel etc will open normally
