Using web browser in a form

Anyone any experience of using MS Web browser in a form. On some machines it
works fine, on others it becomes impossibly slow, (like minutes to load a
form). Have tried decompiling the database and importing it all into a new
database. This sometimes works, but never for long. I am using IE 7 on some
machines and IE 6 on others. IE 7 seems to the worst culprit, but not
exclusively so. All machines are similar speed 2.GHz = 1GByte. Plenty of
HD space etc etc.


Any tips, or just sympathy
