Reusable blocks will always save

Hello.

I have searched the forum and found many posts here regarding the change of reusable blocks in the last few versions, but I think my problem is a little different.

I have made some reusable blocks for a site and every time I enter a page that uses this reusable block, the Update button is activated, and get that dot that indicates that a reusable block has changed. This is just as I enter the page, I have not edited a thing at all.

To add to the complexity, it does not happen all the time. I there a way to see what has happened/changed in the block before saving?

ANy tips?

Thanks

Endre
