My home PC and keyboard are both a little wacky right now.
Here's a link that talks about it:
http://www.astrologyweekly.com/astrology-articles/mercury-retrograde.phpI like this article because they also recommend activities that are good to do during this period (re-doing something, moving slower, double-checking, finishing up projects that were put on hold)
They also talk about the higher possibility of computer crashes, communication problems...

They also suggest that important contracts should not be signed during this period either, and that if you have business plans and travel to make a habit of double-checking during this period
