Tab Function Gone Funny??

[Rich_Lovina]

My form, of some vintage, Access 2000, has suddenly decided after trying to Tab to NextFld, to tab right out of my form, and go to Access main page.
My properties appear as always, so any suggestions from anyone who may have experienced this oddity?

Addendum: However using the enter key now does the right job, including going to new blank record from the last ordered field....so why did tab go permanently funny???

Thanks Pat, you're dead right. I had to re-locate the computer and on start-up, came to the form and tab is normalised. Tks.
