MX2004 gone wonky ... Help!

[Webmzter]

Help! DW for Mac OSX went crazy today. Code View no longer has colors. Just
black type on white background. If working in Design View and hit Return to
create new paragraph, no closing tag is created. Hard coding one in doesn't
help in terms of spacing between paragraphs. Have to use BRs. Also, this all
seemed to start when I tried to open an existing file and it kept crashing DW.
Finally used the Option key to make a copy of the file and put it in a
different folder. Was able to open that, but some of the text had been eaten
and or rendered as a bunch of weird symbols.

What the hang is going on?

I just had this happen to me after using DW for years on a PC. I opened an old
file, heard a "bing" and then code was all in black, row numbers gone and any
file, even ones I was just looking at are now all black with no row #s-- when
you say to delete preferences, what do you mean?
