Sorry, I don't get it. After over two hours of testing with 64bit Linux 
Mint 18.1 Cinnamon and Lazarus 1.9.0 r54833M FPC 3.0.2 
x86_64-linux-gtk2, with new or saved projects, without or with 
AnchorDockingDsgn / Sparta_DockedFormEditor, I'm not able to create a 
crash.

I tried this steps and around:
- Open project
- Select a popup menu (there are several)
- Double click to edit
- Select menu item 1
- Immediatly select menu item 2


If you want, you can add a minimal example and explain every single step 
again, what you do, to create a crash. Then, I'll test again, but for 
now, I don't know what to do more.

What Lazarus revision are you using?
Do you have installed AnchorDockingDsgn, Sparta_DockedFormEditor or 
something similar?


Kind regards
