right click problem

[jash]

Hi
I have a problem which may be part of a larger problem. I'm using a Pentium 4 machine with XP Pro. When In Windows Explorer I right click on a directory to set the properties nohing happens.
At a later time however, the dialogue box will appear - I just can't see what condition is met to allow this.
I'm running IIS: at least IIS says it is running, but it won't work with Macromedia Ultradev to allow viewing of files and testing of asp. I can't get the admin box to open, except that agin, when some conditon is met, it appears. Sometimes it just starts running and all is fine. But I don't know how I get it to run.
This wasn't a problem with Win 2000.
I am really annoyed with it. Any ideas?
