CRCDropper drag and drop CRC32/hash calculator

Some explanation of CRCDropper, CRCDropper 2 and CRCDropper 3:

What are these for?
These are a bunch of small programs that you can run when you want to know the CRC32 value for a file. CRCDropper 2 does the same job as CRCDropper, except you can also drag a file onto the program icon to start up with the calculated CRC and it looks completely different.

CRCDropper 3 is different to the earlier versions - it supports drag and dropping multiple files, and as well as CRC32 it also supports MD2, MD4, MD5, SHA1 and CRC16 algorithms. And it shows the file size in bytes. It's also quite a bit smaller than the earlier versions. (And version 3.0.1 is smaller than version 3. At this rate version 4 could be shorter than this paragraph.)

Why would I want to use one of these?
You probably don't. If you wanted to know the CRC32 value for a file, you would know that you wanted to know the CRC32 value for a file. If you know what I mean. And I doubt if anyone wants to know the MD2 hash for a file.

So why did you write them?
Someone once said "it would be really handy if I could just drag a file from Windows onto a program to find out the CRC value." So I wrote one. Then I wrote another. Then after someone made some suggestions I wrote the third one.

What's new in CRCDropper 3.1?
This is the first version with Unicode string support, so it works better with non-latin characters. Here is a screen grab to illustrate:

It's also the first version compiled with a newer version of Visual Studio and with some minor internal updates that make it bigger than version 3.0.1.
