Subscription problem

I have some problem with project's alerts in Team explorer.

I 've made project's alert with Build completes event. I 've received

e-mail about this event.

However, I've made project's alert with Anything is checked in event. I

haven't received any e-mail about this event.

I 've checked in Tfs_Integration database and I found the record in

dbo.tbl_subcription table with this event and my e-mail address.

It is a bug in Team explorer
