• Which version of WiX are you building with?

WiX Toolset v3.9.1208.0

• Which version of Visual Studio are you building with (if any)?

Microsoft Visual Studio Premium 2012 Version 11.0.6129.00 Update 5

• Which version of the WiX Toolset Visual Studio Extension are you building with (if any)?

Windows Installer XML Toolset version 3.9.1208.0

• Which version of .NET are you building with?

Microsoft .NET Framework, version 4.0.30319.42000

• If the problem occurs when installing your packages built with WiX, what is the version of Windows the package is running on?

Windows Server 2008 R2 Standard

• Describe the problem and the steps to reproduce it.

Minimal repro project for this issue at https://github.com/0ptikGhost/HotKeysRepro

Steps to Reproduce:

1. Launch HotKeysRepro.zip\HotKeysRepro\bin\Release\HotKeysRepro.exe
2. Press Alt+a to agree to the license terms and conditions
3. Switch to any other window
4. Switch back to HotKeysRepro Setup window
5. Press Alt+a to deselect license checkbox

• Describe the behavior you expected and how it differed from the actual behavior.

Step 5 above in Steps to Reproduce should deselect the license checkbox. Instead the license checkbox remains selected. This behavior is also seen with all other accelerators (hotkeys) on the window.

A workaround is to press tab between Step 4 and Step 5 above.

I built the HotKeysRepro project with WiX 3.11 and found the behavior to be different. Alt+a moves the focus to the "I agree to the license terms and conditions" text but the checkboxk is not selected or deselected. You have to press space to select/deselect the checkbox. You sill have to press tab after switching to any other window to get any of the other hotkeys to work.

The reported expected behavior is to be able to press Alt+a (or any other accelerator) directly without needing to press tab or space or any other character combo.

TranslateAccelerator explains what's going on - accelerator keys don't work if parent window is the active window and no child window has the keyboard focus.

The solution is at Dialog boxes return focus to the control that had focus when you last switched away; how do I get in on that action for my own windows? Also need to make sure a control gets focus when switching pages.
