[DXBase] CPU Use Nears 95 Percent

[Joe - WL7M]

As a new guy, I'm experiencing a problem perhaps others have solved.  The 
CPU use rater goes to about 95 percent when DXBase 2003 has been running 
for awhile - a few hours. I have an internet connection running, spotting 
DX stations.  When I close the internet connection, the CPU rates drops 
back to about 4 percent.   Anyone have an idea as to what is causing this 
drain on the resources?  Makes it tough to use after awhile.....
