There seems to be an issue with whether the taskbar is visible or not. DX seems to take it into account and moves objects accordingly.. The problem is that it seems to check it too early or something and positions things in relation to it before it realises it's hidden.

Ditto - very annoying and I hope it soon gets sorted.
I have had this problem since 2.1 first became available.

I've found a solution Adam - Iv'e gone back to 2.0.

you said it !

Don't set it as a dock instead give it a script to act like a dock.

Just use the window edges and and the x,y coords of the object to get it positioned right at start. If you feel like going further you can make it dynamic so it can change sizes on its own, but still be in the right place. You can also make other objects that use a script to set themselves relative to the first. I made a taskbar like this on my own that would change sizes depending if winamp was running: if it was a bar would popup in the middle and blend in with winamp controls on it. If winamp shut off the bar would dissapear and the whole of the taskbar went back to the original size. Also at the edge (it only covered about 1/2 the screen width) I had a weather bar that would change size to accomodate the lenght of the weather string that I supplied it: "windy" would make the bar shorter than say "thunderstorms." It is a shame that I never made my own graphics for it and was to lazy to make them before I had to reinstall windows.

I personally see things like the dock setting as a substitute for scripting. While not a bad thing, you can do more with straight scripting.

If I had it I would

I remember sort of how it goes. I also might have it on a cd somewhere. Give me a little and I will tell you how to.
