OS 10.2.5

[Jerry Bunn]

Ever since I've installed OS 10.2.5 on my Digital iMac, 800 Mghz, G4, I 
have had nothing but crashes on anything Classic I run.  I can open 
Clarisworks and work on a file, but when I close that file and try to 
open another file later, it usually crashes and won't restart.  The 
Clarisworks title page coems on when I try to restart it and it goes 
throught the first stages of starting then simply disappears.   I have 
to restart Classic each time in order to restart Clarisworks.  My 
Gradebook Pro program is similar. I truly wish I hadn't upgraded to 
10.2.5.  I never had these problems in 10.2.4.
Does anyone have any ideas why this might be happening and what I can 
do about it?

Thanks

Jerry
