Problems connecting nodes

[leonard7e]

My PC …
Ubuntu Linux 19.04 (32G memory)
GPU: GeForce GTX 770

This problem occurs suddenly, I am not sure how to reproduce. Normally I can do node connections with a mouse drag from output slot to input slot. But if the problem occurs, this does not work. Instead my clcik-drag moves the whole source node or creates a selection box.

I can confirm this. It sometimes happens when messing with group nodes I think.
Reopening the material doesn't work, and the issue happens with all open materials.

I also have this problem. It is very common to happen, the only solution now is to save and open again.

Yes I know of that problem and I didn't find a way of repeating it yet. there is another (maybe related) problem when several tabs are open and 2 graph editors are vosoble at the same time.
If anyone can find a minimal scenario to repeat this issue, please feel free to describe it here. ;)

Hi. Thank you for your answers. I tried to reproduce issue.

It seems the problem might be linked to node window zoom and number of output slots of affected node.

I cannot reproduce issue with node which only has one output slot. But I could do with nodes which has multiple output slots.

A minimal way …

• create Pattern//Beehive node
• zoom out max
• try connect 2nd or 3rd output of Beehive to Material node
• zoom in again
• try connect Beehive to Material node

After I zoom in max, I was able to connect Beehive again. Sometimes I have to repeadingly zoom in and out to get that behaviour.

For some obscure reason I am able to connect first node of beehive, while other 2 dont work. Could you reproduce?

If I use Workflow // Materials // Wood instead of Beehive, the problem affects first output slot of Wood too.
