Use MikTeX 2.7 under Windows XP SP3. Been using it for a long time, with
generally no problems. This morning though I ran package updater, and
found that one package ((geometry) was completely wiped out. I have 3
different machines I use, so when I saw this happen on one, I made
backups of the geometry folder before upgrading the other machines. Sure
enough, geometry was wiped out on each of them when I tried to run the
package update. If I copy the old files back into the root, check for
updates, geometry was once again reported as being out of date - update,
and wiped out again. Etc, etc...
Can't say whether its the repo, or something more basic. Anyone else
seen this behaviour?
