XP bug in handling zipped files

When XP copies files from a "Compressed folder" into another directory, that is to say, extracts from a zip file, it creates a temp folder inside

C:\Documents and Settings\\Local Settings\Temp 

but forgets to delete the temp folder afterwards if the files are readonly. So, the temp directory fills up...

Microsoft says call 800-MICROSOFT for reporting bugs. In case anyone in the US reads this, they can do so. Meanwhile, I'll post this on an XP Newsgroup as 'bug in extracting read-only files from zip file'.
