Hi ,
i have the same Issue :(.
I tried many ways and deinstall one by one my Modlist to find aout what happens?
I can say for me it happens when i open the Map with "M" and create a Node. Then i try z.B. to Open the Fairing but the "Right-Click" Menu doesnt show up.
Is there a Mod or what is the Problem.
My KSP is 1.10.1
Greetings :)
