[Haskell-cafe] Weird ghci behaviour?

On Unix-like OSes: If I run "ghc test.hs" and then run "ghci test.hs", ghci fails to load up my code. I have to touch test.hs and then run ghci. I can understand ghci refusing to recompile something it thinks it has already compiled. But it appears to refuse to load it into an interactive session - which is less useful. In fact, removing test.hi makes ghci work again. This is ghc 6.6. Anyone else seeing this? -- Dan
