IDA 4.7-> Buggy?

Sorry, but <reset hidden messages> does exactly what it do, but this doesnt
help me or my strings.
I did some other tests:
I started the debugger ->All strings are gone
I pressed <reset desktop> -> ditto
I tried it on Windows98 ->guess what...exactly the same!

In IDA 4.5 a small message with "generating list of strings" appeared when
I did one of this above, but not so in IDA 4.7!
I think here are quite many IDA 4.7 users so can anybody tell me if he has
the same problem or did I simply get a corrupted IDA version??
