I have tried connecting from several remote machines, even over the GB Lan, so it's not a bandwidth issue.
As an example, in Access, I left click on a column heading and "Nothing Happens", If I wait 10-20 seconds, it will react. I can click on various cells, and as I click, the last pick is displayed. It seems that clicking is causing the refresh.
I set my experience to a low setting but it didn't make a difference.
Any Ideas?
