Checkbox disappearing (MinGW)

[Enrico Maria Giordano]

In the following sample, the checkbox disappears when it receives the focus. Please note that the problem shows up only with Harbour and MinGW.

Any ideas?

Code: Select all | Expand

#include "Fivewin.ch"


FUNCTION MAIN()

     LOCAL oDlg

     LOCAL cVar := SPACE( 30 )
     LOCAL lVar := .F.

     DEFINE DIALOG oDlg

     @ 1, 1 GET cVar
     @ 3, 1 CHECKBOX lVar

     ACTIVATE DIALOG oDlg;
              CENTER

     RETURN NIL

It also happens when you add the OF oDlg clause?

[Enrico Maria Giordano]

Yes, same result. This is the files used to build the EXE:

Code: Select all | Expand

q.prg
-fullstatic 
fwh.hbc

This is fwh.hbc:

Enrico, run OK in my tests

[Enrico Maria Giordano]

Thank you. Are you using MinGW? Did you move the focus to checkbox?

There is nobody here using MinGW, please?

Enrico, yes, this sample is build with MinGW 8.10

[Enrico Maria Giordano]

Ok, thank you.

I only use the libraries that are marked.

[Enrico Maria Giordano]

The problem was the MinGW version used (probably a bug in that version of MinGW SDK libs). Using a new version (10.2) the problem is fixed.
