Emulator

This is my first time reporting an issue here, so I apologise if I'm doing
something wrong. I wanted to try out the multiple Wiimote support in
r4736, but I can't configure the wiimotes properly.

What steps will reproduce the problem?

1. Go to the Wii Remote config dialog, click Button Mapping
2. Select a Wiimote (any of them will show this problem)
3. Pick a button to change (any of them will show this problem)
4. Assign any of the following keys to it: up, left, right, down, pageup,
   pagedown (Possibly more?)

What is the expected output? What do you see instead?

• Most keys will work fine, but some keys are trapped by the UI and cannot
  be used at all.
• Using the arrow keys will just switch the focus.
• The PageUp/PageDown keys will work (hit and miss), but the selected tab
  changes when you press them - so it's a problem now that multiple Wiimotes
  are supported.

What version of the product are you using? On what operating system?

• SVN r4737, compiled myself on Visual Studio 2008 (with a custom patch to
  WII_IPC_HLE_Device_DI.cpp to allow selective file replacing; no other
  changes)
• OS: Windows 7 32-bit

Thanks for looking at this guys. :)
