I have a userobject that is used on a window and can't open this object in the IDE because PB says an ancestor or descendant is already open.
I have no windows open in PB the only way to open that object is to close the IDE and open it again.
I don't have a consistent way to reproduce this yet and don't have time at the moment to investigate but this seems to come more when debugging and either the application giving an error on that window or stopping the debugger when stepping through code on that window and returning to the IDE.
