So yesterday I upgraded to 10.4.10 only to discover my Cisco VPN is not working anymore. It gives an Error 51... That was real bad since I have a client that I support using VPN.

I tried everything to revert to 10.4.9 but it is not that easy to roll back a service pack. Eventually I stumbled across an article on Parallel's forum indicating that my problem might be related to the fact that yesterday I also upgraded from 4124 to 4128...

I did the following to fix it:

My wife's Parallels broke today. For some reason it just died when starting up - no matter what mode we tried to start Windows XP in. We tried repairing Windows XP by means of the installation CD, but this caused even weirder errors.

So I ran a Disk Repair and Permissions Repair - neither working.

I then decided I am going to try and upgrade the disk image to the latest Parallels - 3.0. Well, whilst copying the .hdd file this happened:

If you run a Swing application under Parallels for Mac v3.0, and are using Java 1.6 and your direct draw extension is enabled you will find the application never draws (render) it's canvas.

It is not a bug in your code - just turn off all graphics acceleration in XP.

For those interested in following the events related to my 480g project, take note that I sometimes write stuff on ReefCentral that I do not repeat on here. So feel free to visit my thread there.

Actually I was slightly wrong with my observations. The pipe leading from the overflow to the skimmer was actually inclined away from the skimmer - a couple of degrees...

I removed 32mm of wood from the skimmer's base support and replaced it with 25mm polystyrene. It seems as if I have a slight downward slant now. Will start the circulation back up in an hour's time.
