[IronPython] StringIO???

[kbond at free.fr]

Hello,

I do have a problem to import StringIO.
I have seen that you are explaining this error my not having the latest version
of the .Net framework.
How can I check the version of the .Net framewaork installed on my computer?
I think it is the beta 2 but I am not sure.
Thank you for your help.

Here it is the error I am getting:

with the latest build O.7.5

IronPython 0.7.5 on .NET 2.0.50215.44

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.
