Hi Michael! MS>I just found out that the crashes on Milan when the cache was on were MS>due to self-modifying code in the XBRA install routine without taking MS>care of the cache. The whole XBRA stuff is quite ugly What about an extension to Ssystem() for installing via XBRA? The caller must provide the the XBRA-Structure and Ssystem will insert it into the chain in a "save" way Bye Joerg
