Encountered an improper argument.

Could not allocate 494,1 MB for binary buffer: Out of memory.: Not enough space. Do you want to simply determine whether the files are different without using too much memory?

Answer: Yes

Encountered an improper argument.

Pardon?

Comparison results
Different binary files: a.bin, b.bin

Correct.
But what does "Encountered an improper argument." means?

(Why <ctrl>C doesn't copy the dialog text as is usual in windows? I have to copy them by hand.)

Apparently, it's a bug in 5.0 Beta. Is it easily reproducible?

You can in case of standard message boxes. EDP often uses different (custom) message boxes in cases where additional options are (could be) presented.

Yes, it is, but it disappeared in beta 9 beside making much, much faster the message "files are different".
Very good.

I supposed that.
Could you implement a <ctrl>C handler for your message boxes too?

Good idea; will be added to the next build.
