This is a new one on me

Mach 3 seems to run great until I close the program, it'll crash every time except in safe mode.
Has anyone had this problem before?

Here's what comes up.

The problem seems to be caused by the following file;  atiok3x2.dll

PAGE_FAULT_IN_ONPAGED_ AREA

Tech. Info:

*** STOP:  0x00000050  (0xE2AB1F6E, 0x00000000, 0xBF193275, 0x00000001)

***   atiok3x2.dll  -  address BF193275  base at  BF182000,  DATESTAMP  4b738974

I'm running Windows XP Pro SP3
Dell  Inspiron 600m Laptop

Intel (R) Pentium (R) M
Processor 1.60 GHz, 591 MHz
1.00 GB of Ram

Any help would be greatily appreciated.

Try updating (or roll back if you have recently updated)  your graphics card drivers, seems that file is part of the ATI Rage drivers.
