MacBook Pro wakeup issues

What external devices are you using? Are you disconnecting any when the Mac is asleep?

The only device I connect is a wireless mouse (a little two inch long transmitter
connects to a USB port. Otherwise, nothing.

(I don't always connect the mouse, but I can't recall whether or not it matters as
to the wakeup problems.)

My MacBook Pro has two issues on waking up when opening the lid:

1. Sometimes the screen stays black. It appears the machine is still running, but the screen won't brighten. When this happens, no amount of pushing keys or closing and opening the lid helps. I must reboot.

Don't know whether this matters, but I did change my battery under the Apple recall.

2. When the machine does awaken properly, some windows, eg. Safari, TeXShop, and others, have shrunken vertically. I.e., before closing the lid, the windows are the full height of my display; afterwards, they are about half as tall.

Ideas?

I'll try, but testing is difficult (I don't ordinarily remove the little transmitter). Only sometimes does the laptop refuse to wakeup (screen stays black).

The shrinking windows (Safari, Mail, Preview, etc) happens everytime.
