IWP login goes to wrong layout

[sleepinggypsy]

Is anyone having problems with IWP navigating to the wrong opening layout upon a user logging in as a guest? I have both an opening script that navigates to the appropriate layout, and I have also set switch to layout... under File Options to automatically go to the appropriate layout. However, when one logs on to the site (guest/ no pw) the wrong layout comes up every so often. Mostly, the correct l/o appears. I can't seem to figure out why this is happening. FMP bug?
