Connection Manager and connection records

Date Written: 8/30/91

Last reviewed: 8/30/91

When my application quits after using the Connection Manager to create a connection record but before the record is disposed, I can no longer create a connection record. Even if I exit the application and re-launch, it still does not work unless I re-boot. Is this a bug?

___

The behavior you describe is normal for Communications ToolBox 1.0. This has to do with how the CTB manages mapping shareable resources, heap zones, Resource Manager interactions, and all that. If you have a ConnectionHandle in a heap zone which is opened and you then dispose of the heap zone without closing it, the Connection Manager will be confused about life in general until you restart the Macintosh.
