Access 2007 and ACE 12 hotfix
Description of the Access 2007 hotfix package (Access.msp): October 28, 2008 mentions some performance problems when creating an RTF document and using some controls bound to linked tables. Given that 99% of Access form are using controls bound to a linked table this hotfix could be quite useful.
Also a somewhat obscure problem in ACE from my unilingual perspective however to our multilingual friends this could be important. Description of the Access 2007 hotfix package (Ace.msp): October 28, 2008
Note that if you don't need to use a hotfix then Microsoft suggests you don't install it.
(It would appear that unilingual isn't a word according to Windows Live Writer. Oh well. Not that Google is always correct but there are 96,000 hits for that word. And you don't want to know the second word which was suggested by Windows Live Writer in place of unilingual.)
