Missclicks

I just recently started 8 tabling and in the past few days I have made two horrendous missclicks. Each one probably cost me a chance to double up or more. The first I had KK in LP, and it was folded around to a guy in middle position who took about 20 seconds to raise. By then I had shifted my attention to other tables and acted on several hands, but somehow I ended up click the fold button on the table with the kings. The other time I had 88 on a flop of JJ8 and I ended up clicking fold after a bet and a raise took about 15 seconds each.

Except for these two hands, I can't remember ever missclicking before. I think it could be because some people take way too long to act on their hand, so I have to keep darting around from table to table even when I'm involved in a big hand. It is probably something that won't happen as much as I get used to 8 tables, but I was wondering if anyone who plays 8+ has something like this occur frequently.
