Thanks for your explanation, Kovid.
Just a stupid hint I'm nearly sure you are currently aware of, but just in case.
Please notice how I pointed automated actions (Beautify All files, S&R All through all files) where syntax highlighter is useless while working...
I mean, if possible in the code, if they are the culprits for the pseudo-hang, and if you are not actually doing it, you could firstly turn syntax highlighting (and spell checking) off, then perform those global actions and then re-enable them.
Just thoughts...
