I was a beta tester, and my beta license expired yesterday forcing me to upgrade [no down-grade path back to v3]. While v4 has a better 'look', I have seen no appreciable performance to justify the cost - but I'm stuck now in v4 [and more than a little irritated no free license for the time I put in ]. The other irritation is that my new registration is not with my existing account - I have no idea where it is registered. I did follow the instructions, but .... My problem is that when I'm on a webpage that page calls another link, the new page half opens and the system freezes. This appears to be a problem with both Firefox and IE, see reports 15771 & 15887. Believe this is a coherence related problems as it occurs regularly when I used this mode [which I am not now].
