Description Bugcruncher 2014-07-08 05:23:15 UTC 
Problem description: 
If  "Styles And Formatting" pane is visible and some other, currently unknown preconditions are fulfilled LibreOffice will become unresponding for 1/2 minute or so for certain UI actions

Steps to reproduce:
1. From Sart Center launch Complex Calc wor Writer document with
   lots of Styles, I can reproduce the problem with
   Attachment 102119 [details] for Bug 80794
2. Make sure that "Styles And Formatting" pane visible
3. Click "Files" menu item

Current behavior:
Mouse pointer changes to "busy", LibO unresponding, for short moment contents of "Styles And Formatting" pane disappears, sometimes empty File menu pulldwon appears.
After that unsuccessful attempt next click on "File" will bring up menu "File" menu immediately.

Expected behavior:
prompt reaction

More observations:
The problem is reliably related to 
* visible  "Styles And Formatting" pane 
* Document containing some contents, styles and formattings,
  is not visible with blank new documents

The problem definitively needs some more preconditions, I will do some tests to find out whether it depends on Extensions, User Profile, settings or something else.

The problem started with my update from 4.2.4 to 4.2.5
              
Operating System: Windows 7
Version: 4.2.4.2 release
