timer not working in ie

[smkkiran]

this.task = { run: additemsToTable,
interval: 10//10 ms
}
var runner = new Ext.util.TaskRunner();
runner.start(this.task);

in above code i want to fire a function at regular interval (10ms) it is working in all other browsers other than ie
In other browsers its firing the function as interval mentioned but in IE its taking too much time to fire that function. Even though its calling the function repeatedly but not in the interval i mentioned... total operations in other browsers raking less than 5 sec but in IE its more than a minute to complete this timer
can anyone help me on this... thanks in advance

Have you tried using a plain setInterval? IE isn't that precise in the timing

[smkkiran]

var duration = 1000; var tmFunc = function(){ additemsToTable(); };
setTimeout(tmFunc, duration);
i tried like this but this is also not working....

The tmFunc never fires?

[smkkiran]

it is firing the function but not according to the interval i set for it(10 ms or 100ms) its taking different time....
FYI.....i am adding charts into a table in the function
