Hello, I don't know whether this project is still maintained, but I hope so. :-) There seems to be a really annoying bug in the VHS plugin v0.1 (http://www.cin.ufpe.br/~haskell/vhs/download.html) that can be reproduced in VS.Net 2003 under Windows XP Pro SP2 in the following steps: 1) create a new Haskell App-project: module Main where main :: IO () main = return() 2) create 2 function signatures: module Main where f :: Int -> Int g :: Int -> Int -- *** at this point the devenv crashes, or after inserting a new line after "f :: Int -> Int" main :: IO () main = return() Please note that turning off "Auto list options" and "Parameter Information" didn't solve the problem. --- Also, there seems to be some resource-leak in the plugin, because after closing the devenv stays in memory and can only be shut down using the task-manager.
