The Motion Blur filter is consistently crashing Photoshop CS3 when an angle value other than 0 is selected. The error report mentions mmxcore.8BX. I note that this question has been asked before so obviously others had the same problem, but I could not find any solutions here. Photoshop was restarted using Shift-Ctl-Alt, and settings and Prefs reset. In Preferences, the Plug-in folder is not pointing to any old plugin folders and CS3 is the only version of the Adobe Suite on the computer. The P4 computer has 2 GB RAM, and is running well with no other problems. All other plugins appear to work well too, and this is the first crash I’ve ever had with this Suite or the previous one. Can Adobe or anyone else suggest a solution?………..frank

Okay the more I research this, the more I’m starting to see it may be due to the fact my computer is a few years old and Adobe has not considered that sort of thing when writing code. Bo-o-o!
I found this on another web site…(am I on the right track?):

"To disable the MMXCore and FastCore plug-ins:
1. Exit from Photoshop.
2. In Windows Explorer, rename the MMXCore.8bx and FastCore.8bx plug-ins to "MMXCore.old" and "FastCore.old."

Renaming the extensions will make Photoshop unable to open those 2 files which apparently are used to help speed up calculations using the MMX instruction set. You may experience a little slower editing but shouldn’t have crashes anymore using Photoshop.

Unless you give us more info about your setup, we won’t be able to help you: Exact model of processors, motherboard, etc. XP? SP2? Vista? Other programs running.

As I mentioned in my first post, it’s a dual processor AMD machine. The motherboard is a Tyan Tiger, the processors are Athlons and I’m running XP with SP2. Some of this, as far as I can see, is irrelevant as it appears to me that others running ‘older’ AMD Athlons have also had problems with the latest mmxcore.8bx because the Adobe rewrite for CS3 didn’t take these processors into consideration. I’m not blaming Adobe as such because my machine is a few years old, but it would have been nice if they’d posted something on this specific problem.
So far, only the Motion Blur filter seems to be affected, but it’s fine as long as the .8bx file is disabled. Speed wise…well I’m not noticing much of a difference without the file functioning, so for now I’ll have to live with it I guess………….frank

if the processors in use don’t support mmx, you’re losing nothing by disabling the plugins.

Thanks for that reassurance Dave.
What I don’t understand yet though is that I have had previous versions of Photoshop on this computer, and never a problem, even though it appears previous versions had similar files. Why then am I seeing this problem now, and not previously? In any case, at least I’ve eliminated the crash 🙂 Cheers………….frank
