WinHide not working properly.

[Winter Laite]

This script should run without modification i both AHK2 and Keysharp.

SetTitleMatchMode(2)
DetectHiddenWindows(True)

Run("notepad.exe")
Sleep(2000)
WinHide("Untitled - Notepad ahk_class Notepad")
Sleep(2000)
WinShow("Untitled - Notepad ahk_class Notepad")
Sleep(1000)
WinKill("Untitled - Notepad ahk_class Notepad")
ExitApp()

With AHK it shows Notepad for 2 seconds, hides Notepad for 2 seconds, shows Notepad for 1 second, then exits.

When run from Keysharp this error message is generated.

Uncaught exception:

This code is closer to the example on the docs page, and also fails with the same error message:

Run("notepad.exe")
WinWait("Untitled - Notepad")
Sleep(500)
WinHide() ; Use the window found by WinWait.
Sleep(1000)
WinShow() ; Use the window found by WinWait.
ExitApp()

I’ve committed a fix, please test.

Also see if this fixes the bugs in #85 and #34.

Marking as resolved and closing. It doesn’t fix #85 and #34, though.
