Problem in file dlls/commdlg/filedlg.c

[Lozano, Carlos A.]

Hello,

In the line 655, there is a test for when ofnW->lpstrFile
is null
> if (ofnW->lpstrFile)

but a bit later in line 689,690 there is not the same check,
then if ofnW->nMaxFile is 0 because ofnW->lpstrFile is null,
then the line 690 write in a negative pos:
> lfs->ofnA->lpstrFile[ofnW->nMaxFile-1] = 0;

so mirc591t.exe installer crashes when tries change the drive
in the browse option.

Can someone fix it?

Regards,
Carlos.
