In the course of trying to make my
external fix for the KIindle 3 news problem compatible with Windows XP, I discovered that ebook-convert seems to corrupt the Windows XP command.exe environment.
The symptom is that if you run ebook-convert with a recipe, it completes the download but somehow corrupts the environment in such a way that command.exe no longer runs batch files, and if ebook-convert was called within a batch file that batch file terminates immediately after ebook-convert. The built-in Windows commands still work, but no batch file will run--the command prompt simply returns as if you had only hit the Enter key if you try to run a batch file.
You have to close the command window and open a new one to get back to normal batch file operation, so something got clobbered when ebook-convert ran.
This doesn't happen with Windows 7.
Any thoughts from someone familair with ebook-convert?
