Dialog font sizes are using the default Windows size. Enlarging them solely for TCMD / TCC would (1) annoy the majority of users who don't want/need bigger fonts, and (2) require a MASSIVE amount of effort rewriting all the dialogs in 6 different languages. The appropriate way to do this is to tell Windows to scale the display.
I have no idea what you're referring to with "IDE watch references" - can you provide more details?
I've track this to a called script in another folder. If I set watch var in the script and it gets called from the main script, the main script inherits the watch_ed var. I have a dump alias that deletes all *.watch *.bp files it just doesn't look in any other folder. So its not a TCC/IDE problem its a USER error.
