[flexcoders] Tooltip Style

[sk_flexcoder]

I have set the following style for Tooltip in a CSS file, it works fine, 
however when this style is applied the error messages displayed using the 
Validators are showing as empty red dialog boxes without any text in them. I 
know errorTip is derived from the Tooltip is this causing the problem? Is there 
any way I can set the style for the Tooltip without any conflicts with the 
styles of errorTip.

ToolTip {
        cornerRadius: 6; 
        backgroundColor: #fed678;
        color: #333333; 
        fontFamily: Arial;
        fontSize: 8;
        fontWeight: bold; 
        borderColor: #999999;
}
