hm.  Tony, I will do that, but only after some bigger investigation.  problem in
my case is custom DialogProc-callback being installed for message handling, I am
afraid:

Backtrace:

AFAICS, DEFDLG_InitDlgInfo() should be called in any case to allocate memory for
dlgInfo variable and to avoid crash.  in my case it doesn't just maybe for
installing custom DialogProc-callback: dlgProc=0x401260.

in original report dlgProc=0x0, hence Wine's DEFDLG_InitDlgInfo() function there
should be called by DefDlgProcA() before DIALOG_get_info().  thus, the problem
(with software of original report) may be not the same.
