need computer help

[curtains]

If someone knows a lot about computers I need help. Something just happened that can happen on occasion and cost me a lot of money, and I dont know what to do about it.

Basically whenever I open a window on Partypoker and simply leave it where it spawns, if I try to open another partypoker window, it will claim to be open, but will be invisible on my screen. The only way to open a new table is to move the original one and then open it. In general this is not a problem, however just now my internet crashed, and its a HUUGE problem when you are in 8 games, and you need to log back in and get them started up immediately. It took me about 3-5 minutes to get back in them all, in which I lost a lot of chips in the meantime, and even busted from one, as opposed to taking 5 seconds.

Is there anyone here who colud help me figure out what to do? Thanks...
