问下怎样修改idagui.cfg中的"HELPFILE"以便指向本地windows API帮助文件来实现API帮助关联？我的idagui.cfg中的相关部分是这样的：
HELPFILE = "sample.hlp" // Name of help file used by Ctrl-F1
// Please change it as shown below:
//HELPFILE = "WIN32.HLP"
修改成
HELPFILE = "C:\Program Files\IDA\WIN32.HLP" // Name of help file used by Ctrl-F1
// Please change it as shown below:
//HELPFILE = "WIN32.HLP"后在ida的help菜单中External help项变成灰化了，为何？
