I have the backend library compiled. I've started the front end and will hopefully get it finished today during down times.
I don't think iRex supplied an answer to the autoconf issue so I'm still having to build Makefiles by hand. That will be chewing up a bit of what little time I'll have for this.
But I still think I'll have something to take out for a spin later today. Assuming you didn't upgrade to 2.7.1 that is, and based on the download numbers for ipdf that seems to be an all too small number of you out there, sigh...
