Synopsis: Internal Error compiling
Description
The Internal Error below appeared after I hit F7, after doing a minor edit of a comment. This is weird, because a successful compile had just occurred, and nothing significant had changed. I clicked Ignore, but the items in the Project menu were disabled so I exited. On exiting, issue 13031 occurred again, for the second time today!

Problem Report Interactions
This is very bad. After exiting and restarting EiffelStudio, I hit F7 again. The same internal error occurred. This time I clicked the Restart button. When the start-up dialog appeared, I selected Freeze from the combo box. Again the same error occurred. I clicked the Restart button again. This time in the start-up dialog I selected Freeze and Clean. A "Configuration Loading Error" dialog appeared: "Cannot create project in ... You may try again after fixing the permissions." I didn't have that directory open as far as I was aware, so I checked Process Explorer. It found TortoiseProc, and then I realised what the cause was: just before the first failed compilation, I had run an external command: start tortoiseproc /command:log /path:"$file_name" /notempfile This was still running, and it had the project's directory open for some reason. I closed the Tortoise Log window and then tried Freeze and Clean again. This time it succeeded.
