I discoveredthat if you send FM looking for an IP address that it can't get to (or doesn't exist) FM goes through a long, annoying search process that takes about 4 minutes to complete. Best thing is to take a break, and let it finish doing whatever the heck it's doing. On my machine (300 MHz G3) the 4 minutes is pretty predictable. I haven't found any parameters to set to reduce this time, nor have I found any way to make it stop, short of rebooting. So let it go for 4-5 min and save the wear and tear on any open DBs.
