Yes, every post gets read & noted (if worthy).
When submitting bug reports it is also customary to include all your relevant sys specs, eg:
CPU + Speed, RAM, Soundcard, Videocard, Windows OS, DirectX version.
(ok, you've got an IBM Thinkpad laptop, but we need to know more than that)
Also include a list of any extra 3rd party plugins you may have downloaded.
Many people have no problems with v2.70 whatsoever, myself included.
If you want to reset Winamp to use all the default settings, goto the \Winamp dir & remove/delete the "winamp.ini" file. Make sure Winamp is fully closed first. Defaults will be set next time you open Winamp.
The only other thing I can think of here is that you may have some dead links in your playlist. Check that the path & filename of each entry is correct. That's assuming I've interpreted your words correctly, I'm not rightly sure !
