Jim,

You are a life saver - thank you!

I have W2000, but yoru reference led me to look at the version of HHCtrl.ocx and see that i have a newer version than on my other system. I THINK it was installed w/an app i installed the other day...in any case, I wrote over it w/the earlier version, and now i have help again...whew! thanks!

now i just have to deal w/the aforementioned newly installed app.
