@nucky9: same versions of VS-Code and Nim here. @honhon: checked for leftover/crashed nimsuggest instances, none found. Vs-Code's Nim plugin starts multiple nimsuggest instances, one for every folder (Nim package) in the workspace. The problem remains even after a fresh install of Nim and VS-Code.
Narrowed it down: code checking only works for the first folder in the workspace. So my on-the-fly "fix" is to drag the folder to the top position in the explorer panel...
