            Bug ID: 39275
           Summary: Unhandled exception HtmlHelpA after starting Print
                    Shop Deluxe 15
           Product: Wine
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: hhctrl.ocx
          Assignee: wine-bugs at winehq.org
          Reporter: martinrs at softhome.net
      Distribution: ---

After starting Print Shop Deluxe 15, the following error occurs:
Unhandled exception: page fault on read access to 0xfffffff0 in 32-bit code
..
Backtrace:
=> 0 0xf7443422 __strlen_sse2_bsf+0x32() in libc.so.6
   1 0x7b854663 MultiByteToWideChar+0x172() in kernel32
   2 0x7c39a92f HtmlHelpA+0x158e() in hhctrl

I checked the wine source and hhctrl.ocx HtmlHelpA() doesn't behave the same as
HtmlHelpW(), where it doesn't take into account that some command can send null
filename. It seems to just try to get the string length of null thru the
following statement:
WCHAR *wfile = strdupAtoW( filename );
