If you are using Internet Expendition 5.0 there will instance (where) the browser does not respond while displaying web pages. 請老師幫忙翻譯,還有請問where所引導出來的是什麼子句?

Better use of English would be as follows (please note it is Explorer, not Expendition): If you are using Internet explorer 5.0, there will be occasions when the browser will not respond and the web page freezes.
