sooo slow...

am using virtual PC to run labview on my Mac (iBook G4)... and coz I didn't upgrade the RAM, sooo the application running on the virtual PC is sooo slow... arghhh...
no wonder I hate working on my research... I borrowed my friend's laptop couple weeks ago.. DynaBook.. However I only installed LabView version 7 and the subVI files I have saved in my Mac are all saved in LabView version 8, so now I have to save the files again for the old version.
