Thats rather strange. I've never had that happen before and it shouldn't as there is nothing about writing to scripts in the part of the script for the test menu but i'll look into it anyway.
$Parameters = InputBox ("Parameters", "Please input any parameters to run the main script with.")
If Not @error Then
$exe = $AutoItDir&'\SciTE\AutoIt3Wrapper\AutoIt3Wrapper.exe'
$params = '/run /prod /ErrorStdOut /in "'&$Files[0][1]&"\"&$Files[0][2]&'" /autoit3dir "'&$AutoItDir&'" /UserParams '&$parameters
MsgBox (48, "Project Testing", "Make sure all files used by the project are up to date.")
$process = Run ($exe, $params)
EndIf
Thanks for the hint about the upto. that's been changed. I've also added a checker so that files are checked to exist before the project is opened and this also lets you find that file. I'va also made it add file extensions on if they aren't already.
