[Windows] Crash the IDE through find in all files with sandbox source open

[StewBC]

Windows V2019.09.27 repro steps

1. Open the IDE and have it auto-load the last open project.
2. Have no source files open
3. File, new source file, answer NO to add to project
4. Paste in some working code
5. Run in sandbox
6. Close the running sandbox app
7. Click in source window to activate code editor (the pasted code window source)
8. Press CTRL-SHIFT-F to bring up the find window
9. Select Find in all project files, and enter text that is in at least one of the project files (the file is not open in the editor, only the sandbox file is open)
10. Click Find and see the output in the message window
11. Double click one of the output lines. Notice that the source window the line refers to does not open
12. Close the sandbox window and answer NO to save
13. Double-click the line in the message window again, to try and open the source file with the text that was "found"

At this point the IDE goes away (crashes) with no message, as though it was just closed down.

As a variation, at step 11, open the file that contained the found text in the project manually. Now double-click the line in the message window that refers to that file and watch the project switch to the Default0.agc file that does not contain the text searched for.

In another variation, I ended up with Default0.agc being the active text but the Run in Sandbox button not being present on the toolbar.
