You changed this code from v1211:

void CXTColorPopup::EndSelection(int nCurSel)

{

CXTPMouseMonitor::SetupHook(NULL);

OnEndSelection(nCurSel, m_callerParam);

PostMessage(WM_CLOSE);

}

to this code in v1300:

void CXTColorPopup::EndSelection(int nCurSel)

{
CXTPMouseMonitor::SetupHook(NULL);
OnEndSelection(nCurSel, m_callerParam);
DestroyWindow();
}

But the direct call to DestroyWindow makes my Color Popup crash!

A quick debug shows that the EndSelection is called from both CXTColorPopup::OnKillFocus and

from CXTColorSelectorCtrl::OnLButtonUp, making the second call fail.

This is still a problem in v1310.

Hello,

We added flag now to prevent second call:

void CXTColorPopup::EndSelection(int nCurSel)
{
m_bEndSelection = TRUE;

CXTPMouseMonitor::SetupHook(NULL);

OnEndSelection(nCurSel, m_callerParam);

DestroyWindow();
}

void CXTColorPopup::OnKillFocus(CWnd* pNewWnd)
{
CWnd::OnKillFocus(pNewWnd);

if (!m_pColorDlg && !m_bEndSelection)
{
EndSelection(-1);
}
}
