Screen draw bugs?

Question

Has anybody experienced these bugs in Dreamweaver CSS for the
Macintosh:
a.) When you have multiple windows open at once and you "step
back" from them in Expose to view them all at once, some or all of
them display as blank white sheets.
b.) When you drag a window to reposition it on your screen,
it displays in both locations until you click on it in its new
location.
c.) Sometimes when you mousedown + drag your cursor over a
bit of text to highlight it, the highlighting fails to show on the
screen, although the text you have chosen is in fact selected and
can be cut, copied, etc.
d.) Suddenly and inexplicably a page of text will start
displaying in a different font than the one you chose, and you have
to quit and reopen the document to get the font back.
I'm curious to know if I am unique in experiencing these
problems, or whether they are common. I suspect the latter, since I
am using a Mac Pro that is pretty much out-of-box, with the
original graphics card and so forth. Or is there some other
software I could have on my computer that could possibly interfere
with DW working properly.
