Codewarrior Debugging

I'm having a problem with CodeWarrior when debugging a

Photoshop plugin where it seems to randomly decide to only show

me assembly in the source window.



I've read various reports on comp.sys.mac.programmer.codewarrior about deleting different preferences, turning off optimizations, and symbol

limits, and even sticking a DebugStr in to get it to work.



I've tried all of these and sometimes it works for awhile, then

reverts back to assembly again.



Does anyone have any concrete information on why this happens

and how I can consistently fix it?



Thanks.



(Using Photoshop CS2 SDK, CodeWarrior 9.6, on OSX 10.4.3)
