[Haskell-cafe] Windows: openFile gives permission denied when file in use

Hi all, I just received a bug report from a client that, when an input file is open in FrameMaker, my program gives a "permission denied error". This bug is reproducible with a simple Haskell program: import System.IO main = do putStrLn "here1" h <- openFile "filename.txt" ReadMode putStrLn "here2" I tried writing a simple C program using fopen, and it ran just fine. Does anyone have experience with this issue, and know of a workaround? Thanks, Michael
