Weird slinke/slinkx problem...

...I'm not sure if I've developed a hardware problem with my trusty slinke 1.0, or if it's the latest version (1/19) of slinkx, or if it's windows 2000.

Basically, everything works fine for about 45 minutes, then slinkx stops receiving data from the slinke, and in fact "loses" all of the devices connected to all of the SL ports. When working normally, I have two cx-70es players on SL0, and the DXS on SL1. When it dies, if I click on "SL0" on slinkeserv, the devices suddenly disappear from the screen. If I power off the slinke and close slinkeserv, then restart both, it goes back to working. Another symptom is that (when broken) I can no longer save communications settings to RAM on the slinke (ie, if I change baud rate or enable/disable the parallel port).
