Show configuration changes WAY SLOW in 5310

Hi,

I was happily evaluating DeviceExpert 5210 for a few weeks and everything worked fine for me. Then I decided to upgrade to v5310 which I did incrementally installing Upgrade Pack 5210 to 5300 first and then Upgrade Pack 5300 to 5310. Now I have version 5310 and when I open Configuration Change Trend Details windows and click on Show Changes link for a specific change it takes anywhere from 20 seconds to 2-3 minutes to open configuration change comparison window depending on the configuration size. In version 5210 for the same configurations it used to take 1-3 seconds only. I did tests for 3 browsers and here are the results:

1. Firefox 2.0.0.20
Time to open show change window: 20-180 secs
Client PC CPU load: 50% for firefox process
I get a warning window "script is not responding" 1-3 times and I keep clicking "Continue" to finally get the results.

2. Internet Explorer 6.0.2900
Time to open show change window: 10-60 secs
Client PC CPU load: 50% for IE process

3. Google Chrome 1.0.154.53
Time to open show change window: 1 sec - which means that in google chrome it works with no problem.

On the server side there are no related log messages and no CPU load during the time when the browser on the client PC is opening the show changes window.

Please advise how I can make this show changes window open fast in Firefox and IE.

Thanks,
Peter.
