Just out of curiosity, have you tried to replicate this with the latest 1.5.x beta? (I'm wondering if the fix exists, but never trickled back to the 1.0.x stable branch.)
ahh .... no. I generally do not load Beta software (I get into enough trouble with the fully released versions
I might try in on a virtual machine though.
Where might the Beta version be found ?
The latest beta can be found on the main Arduino download page http://arduino.cc/en/Main/Software
just keep scrolling down.
You can install different versions of the IDEs next to each other. I have the following installed (in these paths):
C:\Program Files (x86)\Arduino\Arduino 1.0.3\
C:\Program Files (x86)\Arduino\Arduino 1.0.4\
C:\Program Files (x86)\Arduino\Arduino 1.0.5\
C:\Program Files (x86)\Arduino\Arduino 1.5.2\
C:\Program Files (x86)\Arduino\Arduino ERW 1.0.5\
The windows versions really don't _need_ an installer, so I just download the .zip version, extract the .zip to where I want it, and then create an appropriate shortcut on my desktop. So far it seems to work fine, but I haven't tried with any betas greater than 1.5.2 yet (I think they are up to 1.5.4r2 now). (The earlier versions are for when I find an bug or quirk with the version that I'm currently using, I can go back a few versions to try to find when the bug/quirk was introduced for bug reporting.)
