When I start Lightroom 3.6, my entire computer locks up for 20 to 30 seconds. The hard disc light continuously lights - that's all.
I tried starting Task Manager before starting Lightroom to view the CPU usage - but the display just freezes, so Task Manager completely misses the time during which Lightroom is starting up.
The Event Log doesn't show anything special (or I don't know what to look for).
Even pressing the Capslock key has no effect - the indicator on the keyboard won't light up until Lightroom has finally started (that is, after 20 to 30 seconds).
After this initial delay, all is well.
What could be causing this nuisance?
(Vista Ultimate 64bit completely updated, 6GB, no virus checker except Microsoft Security Essentials and Spybot S&D, LR cache 25 GB, 300 GB free disc space, LR catalogue optimised, almost 5000 pictures in LR database)
Lots of information. Thanks. I don't know what's wrong, but you can try a few things.
I'd try excluding my images, catalogue, and preview cache from the virus checker.
You also might try running a disk checker against your disks.
Also, sometimes USB devices that are plugged in can cause long lock-ups. Bluetooth can be a culprit.
And finally, I'd try renaming my preferences file and see if that fixes the problem. It often does in strange situations. Find it here.
Let us know how it works out.
