Clicking on anything else during the wait makes Calibre grey out and become unstable.

@
polly - here are my additional thoughts to the previous suggestions
The above seems to indicate that tasks that are confined to reading and writing to the database are OK, whereas tasks involving reading and writing to the book folders are the ones running slowly. That suggests to me the problem is file system related.
The trace reports <<
Started up in 3028.98 seconds with 112 books>> That's 51 minutes!!! Perhaps you can confirm that it really took that long, and let us know how long it took to start Calibre before this slowness started.
Do you have a back up of your libraries - if not then I suggest you take a backup of them ASAP. My hunch is that the disk drive on which you have your libraries is on its last legs and generating massive numbers of hardware interrupts - this can really slow things down.
To 'prove' its not something wrong with your existing calibre installation or configuration you could install the portable version and trying opening that 112 book library and doing a couple of task that run slow - if it also runs slowly then we can be almost certain that your problem has nothing to do with calibre.
What sort of device are the libraries on - a regular spinning drive disk inside the computer, an external spinning drive on USB or eSata or a thumb drive - or maybe a cloud drive.
Do you have other data on the drive where your libraries are - eg photos, videos, documents and are you able to access them and add/rename and delete new items.
When calibre is NOT running you could try to
copy that 112 book library (the entire folder) with Windows Explorer to another disk drive - and rename it to have a distinguishing name. Then start calibre, have breakfast, and then get it to open the library you just copied to another drive and see what happens when you do things in calibre - if they're OK then its something to do with the disk drive.
BTW if it really takes 51 minutes to start then where can I download some of the patience you apparently have <grin>
Addendum : are the metadata.db databases a) actually in your library folders, or b) are they on another drive with symbolic links in the library folders - if you don't know what I'm talking about then the answer is a)
