MT buid 171 problem

 
Hello

After installation of 171 built I face a lot of CPU resource taking ( > 93% ) on start and on Profile swithing (VERY slow!)

I'm with winXPSP2 32 G AMD 512 RAM 200 G HDD

It seems to be from a scrip attached to the charts perhaps, for deleting some charts solve the problem
