Questions: GUI, Mouse, DLLs

[David4]

After updating to the actual SC-Version there are a few problems/questions:
The Start-Button [TEXTBUTTON] doesn't do anything. Users always have to doubleclick the connection. Is this a bug?

In an old Version I simplified the GUI to
(TitleBar)
..............----Text "Connect to Support"----
Button_Start............................................Button_Exit
All the users had to do is click on Start (or Exit). Is it possible to do this again with the actual SC?

In the old version the mouse cursor was flickering slow during a connection. Now its flickering very nervous. I'd like to change this. Is it possible?

What does the files "SCHook.dll" and "vnchooks.dll" do? I can't see any difference when I delete these files.

No idea?
