#1108 Windows CB crash due to floating watch window issue on exit while still debugging

[Andrew Cottrell]

Windows 10 (Linux Mint 20.1 did not crash)
Name : Code::Blocks
Version : svn-r12468 ---> local build
SDK Version : 2.11.0
OS : Windows 10 (build 19043), 64-bit edition
wxWidgets Library (wxMSW port)
Version 3.1.5 (Unicode: wchar_t, debug level: 1),
compiled at Apr 25 2021 09:56:34

Steps to reproduce:
1) Open attached project. It is setup for my MSYS 2 configuration and you may need to change the compiler to your configuration.
2) Set breakpoint in line main.cpp:15
3) Start debugger
4) Ensure the watch window is a non docked (floating) window.
5) Close codeblocks with debugger still running by clicking the [x] on top right of the main window.
6) After a few seconds CB crashes on shutdown on Windows. On Linux Mint Cb does not crash

This is not a critical bug as 99.9% of dev should stop debugging before closing CB. I did this as a test!!!

Attached is the crash RPT.

BTW this was detected when I was testing ticket 606 that is good to close as it does not crash if you follow the steps in it....
