MP3 Export adds minutes of silence to end

A song (4:48 in length), recorded with Audacity, exports correctly to a WAV file, which when played with Windows Media Player shows the WAV file to have a length of 4:48. However, when exported to MP3, the length expands to about 7 minutes by adding more than 2 minutes of silence at the end. Otherwise, the MP3 file plays normally with Windows Media Player. I tried importing the WAV file just created and using that Audacity data to create a second MP3 export. The result was the same, i.e. an extra 2 minutes of silence added to the end of the MP3 file. Any ideas? Thanks.

The first idea that pops into my head is to stop using Audacity 1.2.
Get Audacity 1.3.12 from here...
http://audacityteam.org/download/
You can install both, but only use one at a time. Audacity 1.3 Projects will not open in 1.2
Install fresh Lame and FFMpeg software from the same web site and see if the Export problems don't go away.

I took your second suggestion: downloaded and installed a fresh LAME. As a result, MP3 exporting now works correctly (with Audacity version 1.2.6).
This confuses me because I thought the LAME .dll file I had used to work correctly (it's been a while since I created any MP3 files).
Anyway, here are the differences between my old copy of lame_enc.dll and the fresh copy:
Old: dated 9/24/2008 size 478 KB
New: dated 11/28/2008 size 372 KB
Just 2 months difference in the creation date, and it got 22% smaller. And the new one comes with a .def file instead of a .ini file.
Thanks for your help.
