Testing with Wine 1.2rc3, whatsnew.hlp can now be loaded. However, there are
still serious problems. I don't know whether the underlying cause is the same
as for the infinite loop, but I'll mention it here anyway.

Use winhlp32.exe from Wine 1.2rc3 to load whatsnew.hlp. This actually opens two
windows! One titled "Welcome to Dr. GUI's Espresso Stand" has the "Espresso
Stand" image/menu. But the only buttons at the top of the window are << and >>
(disabled/inactive).
The second window is titled "Dr. GUI's Espresso Stand", and has Summary, Index,
Back, << and >> buttons. That window has "Ladies and Gentlemen" text with a
broken image to the left.

Clicking the Summary button causes winhlp32 to crash. Console output to that
point is:
fixme:winhelp:MACRO_ChangeButtonBinding Couldn't find button 'btn_contents'
fixme:winhelp:MACRO_ChangeButtonBinding Couldn't find button 'btn_contents'
fixme:winhelp:MACRO_ChangeButtonBinding Couldn't find button 'btn_contents'
fixme:winhelp:WINHELP_GetWindowInfo Couldn't find window info for espresso 
ve_c/windows/winhlp32.exe: winhelp.c:270: WINHELP_GetWindowInfo: Assertion `0'
failed.
wine: Assertion failed at address 0x68000832 (thread 0009), starting
debugger...
Unhandled exception: assertion failed in 32-bit code (0x68000832).


Also, clicking any of the links in the Espresso Stand image causes a crash.
Console output on doing that begins:
fixme:winhelp:MACRO_ChangeButtonBinding Couldn't find button 'btn_contents'
wine: Unhandled page fault on read access to 0x00020030 at address 0x743fef43
(thread 0009), starting debugger...
Unhandled exception: page fault on read access to 0x00020030 in 32-bit code
(0x743fef43).

I have attached the console output for both cases.
