Well, again, thanks to everyone...I feel rather stupid. I kept reading about setting the brush to "normal," but "normal" didn't seem to be one of my options (that's the story of my life!) so I kept thinking there was something else going on somehow.
But now I know...when something seems like it should be there...use the mouse! Great tip I learned already!
Unfortunately I had to go into the office for a few hours and couldn't continue working on this.
Anyway, I couldn't seem to get the "Normal" option for my brush to show -- I was using the mouse to try to scroll up and down the options list. But thanks to Teecee's suggestion for using the mouse (gee, why didn't I think of that!) - the "normal" option for the brush became available! YIPPEE!
Thanks guys for ALL the help! Sorry to cause all of this fuss....but I can hardly wait to play around with this tonight!
