Thanks for all your work on qucs.  I am currently trying to get digital simulation up and running.  I installed 0.9 FreeHDL and the MinGW32 onto my WindowsXP system.  I installed them under the C:\Program FIles subdirectory.  When I start the digital simulation of one of the example circuits I get an error indicating that C:\Program is not a recognized ....   Do you have any advice on how I should proceed?
Thanks for your help.
