Help. Plugin windows got BIG

[markleemusic]

I installed the new OS10.5.7 update (what was I thinking) and today my plugin windows have all gotten wider. I am in PT8 with the CS2 update. The windows are substantially wider. The basic plugin window is the same width but now has gray blocks on either side of it that take up a lot more screen space.

I also have a blue glowing line around the upper part of the plug in and around the names of tracks. I have no idea if this is the result of the OS update or something I did putzing around. I want to get back to where I was.

I was in OS9 until February and I was thinking I should dump the preferences file but don't know where it is in OS10.

Confused I am. Thanks in advance for any help.
