Mystery Withdrawal Limit at Interpoker
 

I haven't played at interpoker in ages, but I got one of those free $20 for one hand e-mails, so i thought I'd head back for a bit. Anyway, I had the software erased from my system so I had to reinstall it. I reinstall it, log in, and my balance is $0, but my withdrawal limit is $90. I deposit $100 and all of a sudden my withdrawal limit is $190, without even playing a hand. I play my one hand, then cashout for ~$210. I've never been able to clear their bonuses with pontoon, so I don't know how I've accumulated this bonus. Any ideas, and anybody else have this happen?
