I should clarify that the callback below is on CLOSE_CB as well as ACTION of
the OK button on the form. When I close the dialog box with the windows close
button, it works correctly (callback is fired, and IupPopup returns, where the
data is saved). But it does *not* work when clicking the OK button -- IupHide
never returns and all following events are handled inside IupHide.
I tried removing the event callback from CLOSE_CB but the result is the same
when clicking the OK button:

Also here is the dialog setup code in case that helps:
tWIN_DIALOG *win_dialog_show(const char *id, const char *ledFilename, Icallback
callback, dialog_value_callback value_callback, void *data)
{
tWIN_DIALOG *result = calloc(1, sizeof(tWIN_DIALOG));
Ihandle *config = get_config();
sds attr;
int immediate_show = 0;
int x = 0, y = 0;
char *error = sys_load_led(ledFilename); // this function calls IupLoad and
returns the result after locating the file
if (NULL == error) {
sds key = NULL;
// get handles from loaded LED file
result->ok = IupGetHandle(key = sdscatfmt(sdsempty(), "IDC_%s_OK", id));
sdsfree(key);
result->cancel = IupGetHandle(key = sdscatfmt(sdsempty(),
"IDC_%s_CANCEL", id));
sdsfree(key);
result->dlg = IupGetHandle(key = sdscatfmt(sdsempty(), "IDD_%s", id));
sdsfree(key);
} else {
result->dlg = IupSetAttributes(IupDialog(IupLabel(error)),
"TITLE=\"StoneNotes Dialog Load - ERROR\", SIZE=400x200, EXPANDCHILDREN=YES,
RESIZE=YES");
}
IupSetAttribute(result->dlg, "MINBOX", "NO");
//IupSetCallback(result->dlg, "CLOSE_CB", (Icallback)win_dialog_ok_cb);
//IupSetAttribute(result->dlg, "WIND", (char *)result);
IupSetCallback(result->ok, "ACTION", (Icallback)win_dialog_ok_cb);
IupSetAttribute(result->ok, "WIND", (char *)result);
IupSetCallback(result->cancel, "ACTION", (Icallback)win_dialog_cancel_cb);
IupSetAttribute(result->cancel, "WIND", (char *)result);
// .. snip .. removed additional elements on the form
IupPopup(result->dlg, IUP_CENTER, IUP_CENTER);
return result;
}
