We use Lasso 7.1.1 and Filemaker Server 7 Advanced. We were having a little trouble where everything configured ok, but all the data from filemaker comes in blank. Restarting the server restores full function. I could get Lasso to see the fields, etc, but Lasso just didn't want to actually load anything and show it on a page. We're trying to solve this now. When it does work, it's very fast... Of course it needs to work 100% of the time.
