Yes, that make sense. Between 0.7.4 and 0.7.5 Jim made few changes in the code that use features of .Net framework not available in Beta 1, and only available  in Beta 2.

Martin,

Just as a F.Y.I, IP-0.7.5 did fix it the problem, but as you can also see from below IP-0.7.4 with Beta 1 did work before.

Martin,

Yes indeed it is strange since it worked just fine with the previous build. I will upgrade and let you know if that fixes the problem.

Thanks,

Anthony

Strange that someone reported similar thing on GotDotNet forums. I believe that the cause is an old version of .Net.
You need .Net 2.0 Beta 2 to run IronPython:

Martin,

I think that while fixing the 'assemblies in the same directory' bug, a new critter may have been introduced...

StringIO used to work in IP-0.7.4, now using IP.0.7.5 I see the following trackback..
