新手上路，请多包涵

selenium Python调用ie8失败，已经下载了驱动程序IEDriverServer.exe。并且确定其对应环境变量设置无误，因为同时也下载了geckodriver.exe并且放置在同一目录并成功调用Firefox。

代码段如下：

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
import time
import socket

DesiredCapabilities.INTERNETEXPLORER['ignoreProtectedModeSettings']=True

browser=webdriver.Ie();
#下面都不用看了，在上面这句就卡住了


browser.get("http://x.x.x.x/")
handles=browser.window_handles
hPageHandle=browser.current_window_handle
print(hPageHandle)
for handle in handles:
    if(handle!=hPageHandle):
        browser.switch_to_window(handle)
        browser.close()
        browser.switch_to_window(hPageHandle)
        break
browser.find_element_by_id("UserID").send_keys("xxxxxx")
browser.find_element_by_id("UserID0").send_keys("xxxxxxxx")
browser.find_element_by_xpath("/html/body/div/form/table/tbody/tr[7]/td[2]/input").click()
preLen=len(browser.window_handles)
print(preLen)
browser.find_elements_by_link_text("xxxxx")[0].click()
# time.sleep(2)
oaPageHandle=""
while(preLen==len(browser.window_handles)):
    print(len(browser.window_handles))
    time.sleep(0.5)
print("end")
print(browser.window_handles)
for handle in browser.window_handles:
    if(handle!=hPageHandle):
        print("a ",handle)
        oaPageHandle=handle
        browser.switch_to_window(oaPageHandle)
        break
# time.sleep(2)

a=True
while(a == True):
    time.sleep(0.2)
    try:
        browser.find_element_by_name("userName").click()
    except:
        continue
    break
browser.find_element_by_name("userName").send_keys("xxxxxxx")
browser.find_element_by_name("passWord").send_keys("xxxxxxxxxxx")
browser.find_element_by_xpath("/html/body/form/div/div[4]/ul/input[2]").click()
print(browser.current_window_handle)
time.sleep(3)
browser.find_element_by_xpath("/html/body/div[1]/div[2]/div/div/table/tbody/tr[15]/td[6]/li/img").click()

报错信息只给出了异常名，没给出更多信息，最后跟着一大段html语句，用浏览器打开该html语句如下：

报错信息如下：

一些自己的猜测，根据那段html代码，我在想是不是selenium启动后没有连接上IEDriverServer，于是我手动打开IEDriverServer，发现他总是占用5555端口（末尾有图），就去看了源码发现selenium内部是随机选用一个可用端口的，于是手动指定使用5555端口并且运行代码前打开IEDriverServer但是仍然不行，报错信息一模一样
