Cannot drag/drop nodes from palette

[RASelkirk]

Hi All,

It's been a few weeks since messing around with N-R and I've hit a major problem. Whenever I try and d&d any node from the palette, it jumps up to the upper LH corner and gets "stuck" on top of the "Node-Red" logo. Next node I try to d&d replaces previous node in that spot. Nothing goes onto the flow sheet.

Fresh start:

First attempt to drag "inject" onto flow sheet:

Second attempt to drag "link in" onto flow sheet:

Any logical explanation for this anomaly?

Can you open the javascript console of your browser and check for any errors?

[RASelkirk]

I would if I knew how to. I did go to my Pi and check it directly using the Pi's Chrome browser, N-R works fine there. I am (and have been) using a Win7x64 laptop with FF v82.02 to do my tinkering as it hurts my back to sit at the desk where the Pi is located.

I had previously added a userchrome.css file to my Win FF to make some appearance changes. Undid that and N-R is still misbehaving. The only other change I can think of is FF had auto-updated from 81.0 sometime in the past few days...

Well, that's interesting:

This is just after loading the page, no user interactio at all. I have no idea what I'm looking at, perhaps some knowledgeable soul will...

OK, out of frustration I deleted my entire flow all the way back to what the base startup looks like. My project was for cr@p anyways. Did a full deploy on the empty shell, closed browser, reloaded N-R and it is still doing the same thing. I tried my old favorite FF v56.0, same thing. Apparently, something on this particular computer has changed. The only thing I've manually updated was Flash to 32.0...

​

These console errors are from the "clean sheet" N-R with zero flows or nodes deployed. Are they indicating problems with N-R or conflicts with some other program or ? ? ?

Have you cleared the browser cache?

[dceejay]

and do you have any browser plugins installed ? maybe try with them disabled...

[RASelkirk]

First thing I tried, no joy there.

[RASelkirk]

Wooohooo, that was it! Now to narrow down the culprit.

Thanks!

FWIW, it was the add-on "No Scroll" causing the problem. Disabling fixed it.
