I'm seeing something strange with the CHDK-Shell releases on a particular machine.
I figured that since some relases, probably to save download size, the common files for the different gcc versions come in the _base folder, and on first start this gets copied to the gcc folders an then deleted.
On a computer I was installing CHDK-Shell last day, the copying fails. It is a Windows 7 (eng) computer. The copy is unsuccessfull, but CHDK-Shell does not detect this error and thinks it was made, and then it deletes the _base folder. The result is that I get all sorts of errors about wget, tee, etc missing.
But this is not the worst part. After this happens, I cannot focus ANY application anymore, and I need to logout using ctlr-alt-del or restart the computer to get the machine usable again. Technically, the applications do get the focus when I click on them, but then they immediatley lose it, so I have no chance of executing any other operation. It's as if there was an invisible modal window somewhere else. This is reproducible and happens every time when I get the error from CHDK-Shell that I mentioned above.
The easy solution for me was to copy the _base folder manually to all three gcc folders. After that it works like a charm.
I also tried starting CHDK-Shell as Administrator, but this didn't help either, so permissions are not the problem.
So there are two questions: Why is the _base folder copy failing? And why does CHDK-Shell in that case ruin the focusability of all other applications?
