I get the same behavior.
The program I'm running is old: a 16-bit program that was written circa
1999, running vb3run and based on Superbase. It seems to do well when working
with database forms, but popup windows show the same solid grey as in the above
post.
I don't know if it's related, but printing doesn't work either. The
program doesn't seem to know that a default printer has been set, and the
print options button is completely inop. As with other 16 bit programs, if the
default printer isn't set, the printing doesn't work. I have set the
default printer, both in win.ini and the registry.
This leads me to suspect that I'm missing some libraries. I've tried
installing mfc40 and dcom908, both to no avail. Reinstalling with clean .wine
directory doesn't make a difference.
Of course, the software vendor won't tell me how the windows are generated
or what calls it makes to the printing system. (The programmer's words
"Absolutely not").
Happy Trails,
