What I worked out years ago was although Access doesn't use MSForms directly there references to bits of it which it does use so as soon as you open any form those are in memory 'in use'.
I obviously didn't explain myself properly! The VBA IDE is common across all Office applications and it's the references dialog itself (which uses the underlying MSForms technology) that is causing the problem. The MSForms.dll is just the entry points for the technology and the dialog can't tell the difference.
I may be late to this thread, but I got this simple code from the spreadsheet guru blog which works well.
