Hi!

I have a situation, when there is another path of execution in my application when it processes wxListCtrl updates in OnTimer event and in same time I press toolbar button.

To reconstruct the problem I had create simple application, which have main frame and one toolbar button. 

In Create method of it in addtion I start timer:

BEGIN_EVENT_TABLE( MainFrame, wxFrame )
EVT_TIMER( -1, OnTimer )
EVT_MENU( ID_TOOL1, MainFrame::OnTool1Click )
END_EVENT_TABLE()

bool MainFrame::Create( wxWindow* parent, wxWindowID id, const wxString& caption, const wxPoint& pos, const wxSize& size, long style )
{
...
	m_Timer.SetOwner(this);
	m_Timer.Start(10);
}


void MainFrame::OnTimer(wxTimerEvent &event)
{
	int l = 0;
	for (int i = 0; i < 0x7fffffff; i++)
	{
		l++;
		//wxThread::Sleep(10);
	}
	wxLogMessage("From OnTimer");
}

void MainFrame::OnTool1Click( wxCommandEvent& event )
{
	wxMessageBox("In handler");
}

When I run programm it seems look ok, CPU is fully buzy but when I press toolbar button, in 10 seconds MessageBox "In handler" appeares. 

This is very strange for me and this seems the problem of Windows but not wxWidgets. But it is a good idea if it is possible, to store message in queue and not process it until programm in other event handler.

Best Regards,
Oleg
