This is a blast from the past. Just recieved a call about an app that I wrote back in '98. Had no idea it was still in use. Anyway, it has worked fine for the last 10 years. In the last month they report that performance is acceptable with a single user, but when a second user logs in, it slows to a crawl. I have a vague memory of this issue in a FPD app, but for the life of me, can't remember the resolution. The users swear that nothing has changed. Any ideas?

Thanks!
