It doesn't behave that way here. I can choose "clsTestClass" from the auto-completion dropdown which also shows the public
symbols of the class.

The program behaves as expected here even using the uppercase class name, "ClsTestClass". When having difficulties such as this,
it might help to "Compile all" to make the IDE aware of new classes and/or class properties and methods.

There was a discussion of this some time ago. I think it was in regards to me trying unsuccessfully to close open sockets in the
_free method. The issue, IIRC, was caused by the sequence of events that happen when a resource is freed, and, yes, it is to be
expected. Unfortunately, I don't recall exactly how Benoît explained it. I'll have to see if I can find that discussion in the
mailing list archive.
