[BUG+FIX] WPI doesn't properly restore IE debug keys

[Francesco]

Cause

Core.js lacks the proper code to restore the registry keys changed by the launcher

Solution

In core.js delete

	DeleteRegKey("HKEY_CURRENT_USER\\Software\\WPI\\DebuggerRestart");

In api.js delete

SetScriptWaitTimeout();

In core.js delete

function SetScriptWaitTimeout(timeout) // max is 4294967295
{
	position="core.js";
	whatfunc="SetScriptWaitTimeout()";

	var val=0;
	var KeyBase="HKCU\\Software\\Microsoft\\Internet Explorer\\Styles\\MaxScriptStatements";

	try
	{
		if (timeout<0)
		{
			DeleteRegKey(KeyBase);

			return;
		}

		try
		{
			val=WshShell.RegRead(KeyBase);
		}
		catch(ex2)
		{
			if (timeout==0 || !timeout)
				timeout=0x7fffffff;
			WshShell.RegWrite(KeyBase,timeout,"REG_DWORD");
		}
	}
	catch(ex)
	{ ; }
}

replace

		SetScriptWaitTimeout(-1);
		CheckDebugger(false);

with

		RestoreRegistryKeys();

replace

function CheckDebugger(startup)
{
	position="core.js";
	whatfunc="CheckDebugger()";

	var value;

	if (startup)
	{
	}
	else
	{
		if (RegKeyExists("HKEY_CURRENT_USER\\Software\\WPI\\DisableScriptDebuggerIE"))
		{
			value=RegKeyValue("HKEY_CURRENT_USER\\Software\\WPI\\DisableScriptDebuggerIE");
			WriteRegKey("HKEY_CURRENT_USER\\Software\\Microsoft\\Internet Explorer\\Main\\DisableScriptDebuggerIE",value,"REG_SZ");
		}
		if (RegKeyExists("HKEY_CURRENT_USER\\Software\\WPI\\Disable Script Debugger"))
		{
			value=RegKeyValue("HKEY_CURRENT_USER\\Software\\WPI\\Disable Script Debugger");
			WriteRegKey("HKEY_CURRENT_USER\\Software\\Microsoft\\Internet Explorer\\Main\\Disable Script Debugger",value,"REG_SZ");
		}
	}
}

with

function RestoreRegistryKeys()
{
	position="core.js";
	whatfunc="RestoreRegistryKeys()";
	var RegistryKeysBackupKey = "HKEY_CURRENT_USER\\Software\\WPI\\DebuggerValuesBackup";
	if (RegKeyExists(RegistryKeysBackupKey))
	{
		var IE_DisableScriptDebugger_Key = "HKEY_CURRENT_USER\\Software\\Microsoft\\Internet Explorer\\Main\\Disable Script Debugger",
			IE_DisableScriptDebugger_Key_Backup = RegistryKeysBackupKey + "\\Disable Script Debugger";
		if (RegValueExists(IE_DisableScriptDebugger_Key_Backup))
		{
			var PreviousValue = RegKeyValue(IE_DisableScriptDebugger_Key_Backup);
			if (PreviousValue == "DELETE")
				DeleteRegKey(IE_DisableScriptDebugger_Key);
			else
				WriteRegKey(IE_DisableScriptDebugger_Key, PreviousValue, "REG_SZ");
		}

		var IE_DisableScriptDebuggerIE_Key = "HKEY_CURRENT_USER\\Software\\Microsoft\\Internet Explorer\\Main\\DisableScriptDebuggerIE",
			IE_DisableScriptDebuggerIE_Key_Backup = RegistryKeysBackupKey + "\\DisableScriptDebuggerIE";
		if (RegValueExists(IE_DisableScriptDebuggerIE_Key_Backup))
		{
			var PreviousValue = RegKeyValue(IE_DisableScriptDebuggerIE_Key_Backup);
			if (PreviousValue == "DELETE")
				DeleteRegKey(IE_DisableScriptDebuggerIE_Key);
			else
				WriteRegKey(IE_DisableScriptDebuggerIE_Key, PreviousValue, "REG_SZ");
		}

		var IE_ErrorDlgDisplayedOnEveryError_Key = "HKEY_CURRENT_USER\\Software\\Microsoft\\Internet Explorer\\Main\\Error Dlg Displayed On Every Error",
			IE_ErrorDlgDisplayedOnEveryError_Key_Backup = RegistryKeysBackupKey + "\\Error Dlg Displayed On Every Error";

		if (RegValueExists(IE_ErrorDlgDisplayedOnEveryError_Key_Backup))
		{
			var PreviousValue = RegKeyValue(IE_ErrorDlgDisplayedOnEveryError_Key_Backup);
			if (PreviousValue == "DELETE")
				DeleteRegKey(IE_ErrorDlgDisplayedOnEveryError_Key);
			else
				WriteRegKey(IE_ErrorDlgDisplayedOnEveryError_Key, PreviousValue, "REG_SZ");
		}

		var IE_MaxScriptStatements_Key = "HKEY_CURRENT_USER\\Software\\Microsoft\\Internet Explorer\\Styles\\MaxScriptStatements",
			IE_MaxScriptStatements_Key_Backup = RegistryKeysBackupKey + "\\MaxScriptStatements";

		if (RegValueExists(IE_MaxScriptStatements_Key_Backup))
		{
			var PreviousValue = RegKeyValue(IE_MaxScriptStatements_Key_Backup);
			if (PreviousValue == "DELETE")
				DeleteRegKey(IE_MaxScriptStatements_Key);
			else
				WriteRegKey(IE_MaxScriptStatements_Key, PreviousValue, "REG_DWORD");
		}

		DeleteRegKey(RegistryKeysBackupKey + "\\");
	}
}

Use the new attached WPI Launcher.

Notes

The solution #2 of this other fix is required for this one to work.
