After months of faithful service, DVDA 4.0b suddenly fails on me. It renders the various project objects, but seems to get locked up during te object assembly phase. It does this on every project I've tested, even ones that worked correctly last week. I haven't installed any new software on the XP machine, although there was an XP fix on Monday. Could an XP ix do this, or do I have a hardware problem of some sort (maybe a drive problem, or memory, or something)?

Thanks in advance
