It seems to be the way gmail is built. Up until a week ago I was using both gmail and email from my ISP. All worked ok. Checking two places for email was getting a little tiresome so I decided to setup gmail to fetch mail from my ISP via POP and I'd just use gmail. This worked great for a couple of days. gmail would fetch the POP mail every 15 minutes. Then it started to slow down to every 2 hours. A week later and now it's almost 24hrs between fetches. Very annoying.
