As far as I recall, multiple libraries were working before I applied the 6.0.1 update. Now, after applying that update, strange things are happening.
When I use "Open a previously created Toolkit library." and select a library file from My Documents, that file gets copied to a temporary directory and opened from there. The temporary location is
Documents and Settings / / Local Settings / Temp /
I see this file path both on the Toolkit 6 window title bar and at the top of the Library Manager dialog box.
Every time I switch to a different library, it creates a new copy of the library in a new under Local Settings / Temp. So, the copies accumulate there using up more and more disk space.
"Create a new blank library" creates the new library in the proper place. (But switching to a different library and then back to the new library results copies being made, as above.)
This is on Windows XP using an Administrator user account.
