I have discovered a problem with slapt-update-service 0.5.0b in that after it has done the updating, what I find happening is that after it did it's updating routine, I went to to run a program such as Stellarium, for example, the screen goes blank - and the next thing I know, the system is being rebooted

. And slapt-update-service 0.5.0b is located in
http://vectorlinux.osuosl.org/veclinux-7.0/extra/. And no, I don't have the testing repository activated.
