I guess people who get this should just stick with 2.6.8.1?

I am not sure what else to do except stay with 2.6.8.1 as it did not have 
these problems.

  Isn't this the problem fixed by the below patch?  (Sorry I didn't
get sender name when I collected it.)  Some were skeptical this
would fix it but it has worked for those who tried...

  Oh and BTW what is rollup.patch?
