in reply to PAUSE problem

Did you read this passage from PAUSE? In particular, it says
For security reasons you will never be able to upload a file with identical name again. This strict requirement does have one exception: documentation files may be overwritten.
In other words, you have to bump up the version number if you make a mistake in uploading.

Update: You don't have to, I guess, but what's in a version number anyway? As long as you don't go backwards (n.b., Adobe Illustrator) I couldn't care less.
