Open the source code file, eg.
/usr/src/wine-1.2-rc6/dlls/user32/winproc.c
Open the File Navigator window with Ctrl-F9 (left side pane)
Try double-clicking a function name in this pane.
You get:
Access violation at address 00559FCA in module 'EditPadPro.exe'. Read of
address 00000018.
After closing this message you can go on. The function we called positions the
editor at the right place and places focus in the right pane. It works as
expected. The only thing is this message.

This may be connected with windows switching / activating / deactivating as it
is a 2 pane app.

Prerequisites:
After installing the demo app
http://download.jgsoft.com/editpad/SetupEditPadProDemo.exe follow the
guidelines from AppDb
http://appdb.winehq.org/objectManager.php?sClass=version&iId=20710 to properly
configure it for wine. Just 2 simple steps.

Additional info:
The same result as double-clicking can be achieved by clicking once and
following it with the enter key. This does not cause any problems.
Trying to locate the same function name many times doesn't bring the access
violation banner any more. 
It appears only when you try to follow a new function. After that the function
is freed from the annoying message box.

I contacted Jan Goyvaerts, the author of the app. He is familiar with wine and
he says this is a wine bug.

What else can I provide to make it solved? Brothers programmers, this editor is
a powerful crossplatform tool for editing code. It's worth investigating some
time. I spent already several hours to test this bug and report it. Maybe I
should make another report with specific WINEDEBUG options?
