LabVIEW is awesome. But sometimes things don't go quite right, and when something isn't quite right somewhere (maybe a bad bit of binary) it would be great to be able to recompile your code. Mass Compile is great for upcompiling from older major versions, but will ignore VIs that are already compiled in the current version. What I'd like to see is a "Force Recompile" flag in Mass Compile to ensure all identified VIs are most definitely recompiled, especially useful when you call Mass Compile from the shortcut menu in Project view.
Yes, it could take some time, but less time than scripting it and you can use the time to make yourself a nice cup of hot British tea.
