I looked at the delay problem on my Vista32-Business-System with ProcMon (Sysinternals) and it seems the reason for the delay is the following (failing) strange file/pipe access:
Class: File System
Operation: CreateFile
RESULT: BAD NETWORK PATH
Path: \\ˆÍê(Íêðù\PIPE\lsarpc
No clue why this happen only under Vista. Somehow the path seems to be heavily corrupted.
Procmon shows this error just after the timeout passed by and the filealyzer tabs show up.
Besides, the delay happens also if a file is loaded via the file-menu, only that the first General-Tab was already refreshed. Changing to another tab show the filealyzer is waiting for a timeout (on my system 13 secs).
Cheers
