Damaging Ads

I’ve about had it with the nature of these ads.  I have no problem with Rovio making a buck.  I have a BIG problem with them running ads that damage my system.I am using an iPad.  Frequently after an ad has run, the iPad system dock is shifted on the screen.  In the normal landscape orientation, the dock is shifted completely off the screen.  This makes all the apps on the dock unusable.  The only way to fix it is a complete shutdown and restart.I’m not the only person with this problem — Apple’s support forum has many people reporting the same thing.  This should not be happening.  Rovio needs to address this ASAP!!
