Panic in disabling MenuItem #7

Closed mrpalide closed 2 years ago

mrpalide commented 2 years ago

I want switch from getlantern to your fork because of cgo free, but I get this panic:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x90 pc=0xa35ced]

when trying to run this part of code:

mLink = systray.AddMenuItem("Open UI", "Open UI in browser")
mLink.Disable()

Actually it works fine on getlantern. :(
