How to wire in Altium Designer 08

I'm new to Altium Designer. Before I used PSpice, Electronics Workbench and Proteus.

In these three schemtics software, after you make the wire connections of a circuit element, whereever you drag it the wire connections too will be redrawn accordingly to the new location.

But in Altium Designer, after you drag a part to a new location, its wire connections become disconnected. Like in the screenshots below:

Am I doing the wiring in a wrong way?
Or does it happen this way in this software?

Press CNTR before you start dragging the object

Thank you very much!
I it works perfectly now.

By the way, why the first letter of "A l t i u m" is printed as "@" instead of "A" in this forum?
Does anybody know anything about this?

I have one more question about buses.

**broken link removed**

I want to connect the output of the IC to display (A1 to a, B1 to b, and so on) by using a bus.

I placed bus entries as seen in the picture, and connected the IC to the display via those bus entries.

But how am I supposed to match the bus entires on both sides (A1 to a, B1 to b,... etc)?

I mean, when placing the bus entries I didn't select anything like "this bus entry will receive the data from A1 entry on the other side"; how am I going to make the schematics editor understand it?

Is there a settings page for the bus element?
How do we use buses in Altium Designer 08?
Is there any tutorial for basic shematics design?


EDIT: I know the number of entries does not match on the both side in the image, please just ignore this mistake.

Actually I find this very inconvenient. Of course holding CTRL button while dragging will move the wires too, but accidents can happen and the parts may become disconnected. Is there any way to change this in the setup?
thnx
