no warning when a file was changed from another instance

[Mike Gerber]

Using HomeBank 5.1.7, it is possible to open the same file twice, and then make changes in both instances. When you save them, you lose one of the change sets.

Yes it is, like with most programs.

[Mike Gerber (mikegerber)]

Try to do the same using e.g. LibreOffice Writer: It locks the file and you can't open it twice.

- KeePass keeps a lockfile
- Octave detects a change "from another application"

Those program you mention are single instance (you cannot open the program more than once), HomeBank is not. And I don't like program with this behaviour.

Some software lock or warn, some not, it is an intentional choice. Inkscape and others software I use are multi-instance, this offers flexibility, but of course requires to know what this implies and be rigorous on files you edit, the bottom bar shows several instance after all.

The only way to achieve lock/warn or whatever restriction is to turn HB into a single instance application, If I do I will maybe annoy users that use HB like this. So not sure I will change this for now.

Maybe we have a misunderstanding: I agree, a restriction to run only a single instance of the program(!) would not be good, as you may want to have two different files open at the same time. However, you don't want to edit the same(!) file with two instances of the program, as this may easily lead to data loss. The latter happened to me.

So I see two possible solutions:
1. Lock the file
2. Detect changes on the file from outside (e.g. another instance of HomeBank)

Thanks for considering this :)

added a warning in case the modified time differ between load and save
