It doesn't do that for me.
Questions:
- "Edit Metadata" is Edit Metadata individually?
- Do you have more than one book selected?
- Is it scrolling the selected book off the screen?
- Does it happen if you open Edit Metadata then immediately press OK without changing anything?
- Is it affecting horizontal scrolling as well as vertical scrolling?
- What plugins do you have installed?
- Did this behavior start immediately after you upgraded to 6.17? If so, and if you are willing to take the time, does it happen with 6.16?
- If you run calibre in debug mode, are there any messages?
