Is that all of your sketch, just blink with bigger numbers?
delay(500) delays for 500milliseconds, or 1/2 second.delayMicrosecond(100000) delays for 100,000 microseconds, 100 millisecond, 0.1 second.
I can't see any code, and I'm not sure how this is an "Installation and Troubleshooting" question, but other than that, this is an interesting problem.
I guess this is the problem with IDE... so maybe Troubleshooting And you can use Blink as code.
But we can't see any of your code. If we could, it may prove to be a Programming problem
... but I believe my library does not affect the rest of Arduino.h ...
There is an internal function named init() which is used to set up the timers for (among other things) the timing functions. It is called immediately before setup(). Rename your init() function to something else and that should fix the problem.
