[Lazarus] Switching projects causes Access Violation

[Graeme Geldenhuys]

Hi,

I'm using Lazarus 1.1 LCL-GTK2 64-bit under Linux.

     Lazarus 1.1 r38729 FPC 2.6.0 x86_64-linux-gtk 2

Every now and again, if I switch between projects, then Lazarus IDE 
throws and Access Violation with the dialog warning about data loss and 
the usual OK or Cancel button.

I ran Lazarus from the command line and used the IDE until I got that 
error again - it didn't take long. Only recently did I start using the 
Anchor Docking add-on, but I can't remember if this issue occurred 
before I used Anchor Docking. I'll disable it now and keep using Lazarus 
IDE and see if the same error appears.

I don't know where the issue is... IDE, Anchor Docking, Project 
Inspector window etc. But just it case, my anchor docking layout is as 
follows.
