I use ZP4 (designed to be used over a network as a dde server). Put it on a fast Win95 server and it runs at the same speed through local DDE and across the network via netDDE (actually a little faster via netDDE). Put it on an even faster NT server, and it runs fast locally, but across the network runs slower than snot (a technical term). <br><br>Tests with dummy connections (hardcoded data which required no disk access to pass pack and forth) help demonstrate that the slowness is in data being passed accross the netDDE connection, not time required to run on the server. <br><br>Any ideas what could be causing this, and how to solve it?<br><br>Thanks<br><br>gar
