I have an Access 2010 database that uses a number of forms / reports most of which have DLOOKUP functions. On many different computers / laptops the forms work perfectly, but on one laptop, a very new (<6months old) Lenovo thinkpad running Windows 7 professional, every field on every form or report that uses DLOOKUP, on opening shows no data until the F9 (refresh) key is pressed or the field is entered. All the lookups then display correctly until the form is reloaded or a report is scrolled when, once again, the DLOOKUPS are blank and need to be manually refreshed. There is also a constant "calculating..." indicator on the bottom left of the Access screen, although the application is perfectly functional otherwise.
This only happens on the one laptop and as far as I can tell there are no differences in configuration on the affected machine. Another relevant point is that about two months ago the forms worked perfectly on this same laptop.
Is there an Access (or other) setting, hidden or otherwise, that could have changed to cause this?
