Re: Multiple loops interrupt each other :(
If you do use timers, *do not* use the standard Windows timers. You
should use Multimedia Timers (which are accessed with a different set of
Windows API functions. I don't know if this sub system is supported by
any Euphoria wrappers.), which are guareteed to have a resolution of 1
millisecond.
The problem with the standard timers (setTimer, etc) is that they have
NO guaretees whastsoever. That means that if you ask for a timer event
every 500 milleseconds, it could be a second or more between the actual
events. Worse, there could be a whole pack of backed up events that you
get really fast. This could burn out your motors.
