Description:

Today I tried the IDE Docking Layout:

1. Lazarus v2 RC1 32bit on Win10 64bit.
   (other systems (I can't test) probably have the same problem)

2. IDE docking-layout (anchordockingdsgn.lpk installed)
   (IDE nondocking (floating) layout doesn't cause the crash)

3. IDE two-column docking-layout:
   Left column: Object inspector
   Right column: Source editor at top and Pagecontrol at bottom.
   The Pagecontrol contains as tabsheets:
   Messages, Search Results and all (9) Debug Windows.
   Code Explorer is not visible (has been closed with its red button).

4. The loaded project is a new application (empty form)
   (This might be irrelevant.)

5. When I click "View / Code Explorer"
   ( only Code Explorer is causing the crash, other IDE Windows are OK).
   then the IDE is jumping/flickering wild on screen, many times per second.
   After some seconds Lazarus becomes invisible, except for its Pagecontrol,
   and a modal message appears: "Access violation".
   Clicking on this message closes the IDE after another few seconds.

In summary, Code Explorer can't be used together with this IDE Layout.
