I spent the better part of the last hour trying to A) Get Photoshop Elements to stop CRASHING (quitting for you macfolks) and B) figure out how to make a screengrab on the mac (G5 - dual 2GHz processors, 1GB RAM, 160GB HD...AR! AR! ARRRRR!)
After several panicked emails to Mike H and IMs to Derek, I went to the Adobe forums and then trashed the PSE prefs. If it starts crashing again, you'll hear much screaming and gnashing off teeth emanating from my office.
Then there's the screen grab issue. On the pc, there's a nice little key on the keyboard that says 'PRNT SCRN'...PRINT SCREEN!! This saves a copy of your entire screen to the PC's clipboard. I then open a new file in Photoshop and click 'Edit < Paste'. Ta Da! And in just 4 steps!
On the mac, it's a different story. Apparently, there is no keystroke/shortcut to do a screengrab in OSX. You have to open the 'Grab' utility. Then I couldn't figure out how to keep PSE on top while I opened Grab. Finally, I got it to take a screen grab using the 'Timed Screen'. After 10 seconds, it makes the screen grab, then you have to save the file, and THEN you can open it in Photoshop. Seems a bit involved, doesn't it?
UPDATE: Derek sent me a link from apple.com that explained how to do a screengrab to the clipboard using SHIFT+CTRL+COMMAND+4 , and it worked! Though I feel like I'm putting some sort of left-handed vulcan nerve pinch on the keyboard...
Thanks to Derek and Mike for the help!
