I've noticed this as well but couldn't find anything abvious, that would cause 
this delay. Therefore I assume, that it is Qt4 that is causing this slowdown 
by repeatedly querying the model for some data. 

There is delay visible, when a Python file entry is expanded. This is caused 
by the parsing and processing done by eric4 in order to show the classes, 
methods, ...

In the Others browser, the behavior is different. Directory items are 
populated, when they are expanded.
