My modaless dialog box doesn't work on win3.11 but works on win3.1 and win95
It is 16-bit windows application, MS Visual C++ 1.51, compailed on both win95 and win3.1.

I do not have compiler on win3.11

I had a similar proble with win3.11 earlier.
Does anybody know what is the difference? Compailer settings or something else?
