Main Form is VERY slow to close!

[joebox8]

My main from takes 1min 43sec to close(A lifetime!) everytime. What could be causing this? I reckon it has something to do with the linked tables to another db... any help would be greatly appreciated as this delay would not be loved by the bosses!
Thanks
