Multi-Rooming with Absolute

[Lebronomania]

Because of the 4 table limit at party / empire, I'm forced to play multiple sites to play the number of tables I want. Between sites like party / empire / multi / pstars / paradise, I have absolutely no trouble going from table to table, site to site. But Absolute is a whole 'nother story. When I play Absolute along with another poker client, my computer starts to drag, said drag getting worse and worse over the course of the night, especially when I try going from an Absolute table to a table on another site, or vice versa. If I remember correctly, I used to have the same problem with UB, and I had problems with Absolute on my other, older computer too. Anyone know why I'd have so much trouble with Absolute, and not Pstars, for instance? Any suggestions to rectify the problem? OS is Windows XP. Thx.
