Electrum Wallet: zero mBTC balance after sweeping private address Have the newest (3.+) ver. of Electrum Wallet.  I performed the sweep of the private address to acquire BTC from paper wallet . 
Wallet menu->Private Keys-> Sweep.  Performed the operation, the screen showed me the entire amount in the paper wallet minus (I assume) transaction fees.  

It's been about 12 hrs since sweep, the Electrum shows 0 mBTC balance, History is empty (I checked all addresses generated by Electrum W).  What advice would you have how to proceed from here and check where the funds are?   Electrum W. has rather non-intuitive manual and all the functions I try are giving me no response w.r.t. any incoming funds .
obv i would check the paper wallet address to make sure it is empty.

if it is, then i would input the tx id or the btc address into Blockchain and see what's up.
if you swept it correctly, then the funds are there somewhere.

also, if the amount swept was a lot and your fee was puny, be prepared to wait a very long time.

i see SO MANY NOOBS try to transact 5/10/40 btcs at once and pay a fee of $3!!!!!
not saying you did that....just saying
