Some interesting observations:
Switched to DALVIK & managed to load & run AUTOMATIC CACHE CLEANER,no issues.
Switched back again to ART & found same app to be completely uninstalled from my device.(Hadn't seen that on my GPE MOTO G).
Talk about coughing up the proverbial hairball.... 
uke:
Still have the same issues w/SWIFT KEY (strange number input issues). Could be the site that I was entering acct # information with,as it acted exactly the same w/all other variables identical.
Perhaps the SWIFT KEY issue is a bug that the developer needs to take a look at,as my other KIT KAT devices don't have this issue.
a BTW:
Might wanna place your phone next to a fan when switching from DALVIK to ART,the back of the phone gets quite warm.
Probably not enough to cause any harm,but,if repeated numerous times,could possibly zap a little life out of the battery.No one wants that.
Also,when switching from ART to DALVIK,this isn't necessary,it only takes about 3-5 minutes,vs DALVIK to ART's 20-30+ minute switch time.
Here's an informative post on the subject,for those that are interested:
