[DXBase] internet cluster window + AR-User program

2003年8月24日 09:13:07 -0500

Lee, VE7CC
I tried your AR-User program, it works perfectly with DXBase2004. In
particular I like it's ability to set AR-Cluser filtering options use the
mouse! As a AR-Cluster sysop I get regular questions about how to set
filter options...your program makes this a breeze. And no 100% CPU usage if
there is a disconnect!
Nice Job!
