Button issue at Party (multi tablers)

[MobbDeep]

Post here if you have the problem with disappearing buttons at Party while playing more than 4 tables or not.

For me it works fine if I 4 table but I'm starting to loose buttons sometimes when 5 tabling, gets worse the more tables I add.

I have a AMD Athlon 3200+ with 1 GB of RAM, and I've tried all the things suggested by Party Poker...

With this post I wan't to see if it's possible to 8-table without loosing buttons or if it's impossible even if you have a "NASA" computer.
