|When a program stops responding, I like to give it a minute and let it work. If nothing changes, I continually click the window's title bar. Lastly, I'll open Task Manager and continually try to end that program task and reload the program.|
There's no specific reason why a program stops responding. I suggest keeping it updated, which means installing Windows Live - Mail for XP. http://explore.live.com/windows-liv...
Outlook Express is no longer supported and Windows Live Mail for XP is the last supported one for that operating system. XP can't run the latest version of WLM either.
Then there's general computer slow down suggestions like scanning for malware, cleaning up temporary files, and cleaning out the dust with a can of compressed air.
