To see how fragmented the cache is, go here:
C:\Documents and Settings\YOUR NAME\Local Settings\Application Data\Binary Boy\Cache
Then load binboy.bbcx into notepad or another text editor and scroll down to the newsgroup name. The ranges of previous refreshes will be on the next line. For exmaple: 736694-786693,787087-792226
If you do a refresh ALL, it will normally make no more refreshes than the number of ranges+2. In most cases it can eliminate some requests based on the range available from the server.
Does the bbcx file show lots of ranges for that newsgroup?
