Hi,

My app crashes intermittently when I open new windows. I'm using one (hidden) tab and a navigation bar with a hierarchy of windows. The example below shows what (sometimes) happens when I try to open a blank modal window:

My code, first -

var searches_win = Titanium.UI.createWindow({
    barColor:BAR_COLOUR,
    backgroundColor:'#336699',
    title:'Recent Searches'
    });
var b = Titanium.UI.createButton({
        title:'Close',
    style:Titanium.UI.iPhone.SystemButtonStyle.PLAIN
    });
searches_win.setLeftNavButton(b);
b.addEventListener('click',function() {
    searches_win.close();
});
searches_win.open({modal:true});

Crash, and output:

[74429:207] *** -[NSCFNumber _tabBlur]: unrecognized selector sent to instance 0x504c640

Has anyone else encountered an error like this before?

Thanks!
