Error when loading multiple thumb files

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Select multiple Thumbs.db files and drag them into the application window.
2. Only the first Thumbs.db file is loaded correctly.
3. An error message is displayed for each of the remaining files.

What is the expected output? What do you see instead?
I expect that all the Thumbs.db files are loaded and their thumbnails are 
listed in the application window.

Error message: "The database file failed to open."

What version of the product are you using? On what operating system?
1.0.1.9 on Windows 7 and 8

Please provide any additional information below.
Thanks for a great application. Being able to batch load multiple thumb files 
would be amazing.

I'm unable to reproduce this issue. I've tried testing it on various Windows 
systems as well as through Wine on OSX. Everything seems to work fine.

That particular error message has to do with the system failing to open the 
file. There's a specific reason why it fails, but I don't have things coded in 
to display it. However, I can release a debug version of the program that will 
do that if the below tests don't narrow the problem down.

For the sake of testing, try moving all the Thumbs.db files into a root folder 
such as "C:\TEST" so that the files have short file paths. Also make sure that 
the Thumbs.db filenames and file paths don't have any Unicode characters in 
them. See if you can drag and drop them from this new test folder.

If the first file loads, then there should be no reason why the others don't, 
but see if you can also load each Thumbs.db file individually.
