Problems with TAB_GetCurFocus

Hello,

I'm having problems with the result of the message TCM_GETCURFOCUS. In
Windows, it returns "0" while in wine I got -1 (0xFFFFFFFF). This
results in a Segfault for a 3rd party proprietary application (no
source).

Sometime in the past, wine 0.9.24 (suse 10.2), this app worked
flawless. I filtered just TAB/TCM messages for version 0.9.24 and
current. For current wine (0.9.48), I got:

The line:

fixme:tab:TAB_GetCurFocus we have not to return negative value

In 0.9.24 log migth be intersting... I guess the message
TCM_GETCURFOCUS should never returns negative values. BTW, the test
file test/tab.c expects -1.

         /* Testing CurFocus with largest appropriate value */
         SendMessage(hTab, TCM_SETCURFOCUS, nTabs-1, 0);
         focusIndex = SendMessage(hTab, TCM_GETCURFOCUS, 0, 0);
             expect(nTabs-1, focusIndex);

         /* Testing CurFocus with negative value */
         SendMessage(hTab, TCM_SETCURFOCUS, -10, 0);
         focusIndex = SendMessage(hTab, TCM_GETCURFOCUS, 0, 0);
             expect(-1, focusIndex);

         /* Testing CurFocus with value larger than number of tabs */
         focusIndex = SendMessage(hTab, TCM_SETCURSEL, 1, 0);
         todo_wine{
             expect(-1, focusIndex);
         }
