Moving nodes via keyboard stops working

Folks, I'm stuck.

I use Firefox - latest version.
NR 4.9
Ubuntu 22.04 LTS

Usually I select nodes and use SHIFT and arrows to move the node.

Now and then this stops working and the whole screen shifts.

What's going on and how do I get it back to moving nodes rather than scrolling the screen?

Obvious questions first:

Node RED version?

Have you seen this behaviour with other node-red versions and/or other browser's?

Does it happen while in the middle of moving a node? After a certain amount of key presses?

Does it only happen after (for example) opening a node edit panel?

Does it continue to happen for ever more until you refresh the page?

NR 4.0.9

Sorry, missed the middle 0 in the first post.

Yes, this happens from time to time with a lot of NR versions.

But I don't know what triggers it.

It is localised to THAT tab.

If I go to another TAB, the nodes move as expected.

By the sounds of that, it doesn't just happen in the middle of a move operation. I.e you're not in the middle of shifting a node pressing the keys and suddenly it stops working, right? It's more that you decide to move a node after some time of doing various tasks and it just doesn't work. Does that sound about right?

A lot changed in node red 5. Do you have a version of node red 5 and have you seen it on that?

An answer here would be a good clue for us Andrew.

Thanks,

I stupidly didn't think to try that.

Seems to have fixed it.

Sorry dude.

I'm getting a lot of brain farts these days.

Oh, it was a SHIFT RELOAD I did.
