I've tried four times to update to build 5626 from build 5608. Sometimes, the update doesn't show up in Parallels Desktop (running under OS X 10.5.5). When it does show up and I download the update, the resulting dmg file is always a different size from the time before; it hasn't been the same two times in a row. The latest attempt resulted in a 110.7MB file. Each time, the dmg file seems to be corrupt because it can't be mounted. I'm growing tired of playing with this. Any suggestions?
