[Ti] Your opinions about using/ not using DiskWarrior for Tiger (3.0.3)+ problems using Mail & PS CS2

[Ettenberg Frank]

Dear List,  I have noticed that Photoshop CS2 & the Mail program  
occasionally have attacks of the mysteriously long-turning
rainbow wheel - when I just start using these programs on my 1.67 G4  
aluminum PB.  I have 1.5 gig ram installed-so why should there be
this slowdown?  Would using Disk Warrior for Tiger help or not?  I  
have a feeling that the problems with the above apps is a separate  
issue.  In any event I'd appreciate your opinions on the validity of  
using DW at all...& what I might do - if anything - to remedy these
chronic software problems.    Thx   Frank Ettenberg
