In the past, users were able to scroll either side of the diff window using the wheel mouse. It looks like in Netbeans 8.1 the left side of the diff (the old version of the file) is no longer scrollable.

I am expecting to be able to scroll the left side such that even if I use the wheel mouse in the left window, it applies to the scrollbar in the right window.

Can you please try the newest build?
I've seen this issue in some old dev build, but in the newest daily build it works fine for me. 

Unfortunately I cannot find any fixed issue related to this, so I'd like to know if it relay work in the current daily build or it it is somehow "random"

Thanks

I can reproduce it consistently in build 201601130002. Does this help?

To reproduce:

1. Open a Java file in the editor.
2. Click History (meaning, local history)
3. You should be able to scroll on the right panel, but not on the left.

Thanks for info, I can it reproduce now. 
The trick is to use diff in local history. Diff for two files (from context menu->Tools->Diff) work fine for me.

Milo, this seems to be caused by your recent changes in DocumentViewOp: adding MouseWheelDelegator. I don't know how it should work but it kind of disconnects scrolling from all our diff views. If I comment all lines in MouseWheelDelegator.install, it starts working again. Can you please take a look?
