My StrataFrame-based menu system launches VB6 exe's. Session locking does not seem to work when any of the VB6 applications are active, but it works fine if there are no VB6 applications active. Is there a work around to make this work or someting I have to live with until the VB6 apps have been replaced? Did you guys experience similar issues when launching your FoxPro applications?

The form locking does not work with session locking when a VFP form is up.  However, since we are using Windows API calls to "hijack" the parent of the VFP forms when they are shown (to bring them into the .NET MDI container), we are able to still lock the session because everything is just minimized.
