[FIXED] [#1378] [4.2.0] Tagfield memory cpu problem

[Fergus]

Hi,
There seems to be a problem with the tagfield control.

My page was taking up a lot of cpu usage and i finally narrowed it down to the tagfield.

if you run the following code...

        <ext:ResourceManager runat="server"></ext:ResourceManager>
        <ext:TagField runat="server" ID="dd"></ext:TagField>
        <ext:TagField runat="server" ID="TagField1"></ext:TagField>
        <ext:TagField runat="server" ID="TagField2"></ext:TagField>
        <ext:TagField runat="server" ID="TagField3"></ext:TagField>

and then click on one of the tagfields you will see cpu usage for the browser go up and stay up even when page is idle (about 5% to 7% on my laptop).

On my live page i have 3 tagfields with items in them and on a slower laptop my cpu usage jumps to over 50% and stays there. Making the page very unresponsive. This happens both locally and on live server.

I have tried it on several different computers and with Ext.Net V3.21 and V3.3 and in Chrome and Firefox
