Checking bookmarks for changes

[Dan Carlson]

For the past few months, there's been something nebulous that's been 
nagging me about OmniWeb 5.  It's unconditionally great, and I 
absolutely love it, but something seemed off every once in a while.  
And I finally realized what the problem is -- the automatic checking 
for refreshed links isn't working according to the schedule I've set.

Specifically, I keep all of my RSS feeds in a bookmark folder called 
"News Feeds".  I've set the "News Feeds" folder to check for changes 
every hour.  But at most, I've noticed that I'm getting updates once or 
twice per day.  And so I often end up opening the bookmarks window and 
manually telling OmniWeb to update the links.  But this can sometimes 
get a little annoying, though I never even really thought too much 
about it.

Is there any indication that the auto-update of RSS feeds isn't working 
properly?  Do I have a setting improperly established?  What's wrong?

Thanks,
