IE7 grid is slow, Firefox ok and Chrome too

Hi,

I'm testing my grid with 105 records and the rendering is unusually slow with IE7. I've tried this code:
obj.setVirtualMode(obj.getRowCount() > 20 ? true : false);

but don't get any improvements.

In Firefox 2.0, rendering and loading time are perfect and in Chrome as well.

Is there something else I could do to improve this?

My table data is taken from a MySQL database.

Here is a sample data of a row:

["<a href=\"edit_record.php?id=1&table=Registrations\"><img src=\"images/editIcon.gif\" width=\"18\" height=\"16\" border=\"0\"/></a>","<a href=\"delete_record.php?id=1&table=Registrations\"><img src=\"images/deleteIcon.gif\" width=\"25\" height=\"19\" onClick=\"return confirm_deletion()\" border=\"0\"/></a>","1","2009-09-10","Testing User","Canada","tester@tester.com","123-456-7890","2"],

Could the img tags actually slow down the browser? Is there any patch for this?

Thanks

Is it still slow with obj.setVirtualMode(true)?
