Here's A Tip --- When you have a question about Photoshop and come to this forum, some of the best and most immediate help is that which you obtain yourself by the following approach:
1. Read the FAQ in the link at the top of the forum; if you're using a newsreader, I don't know where <remove the crack> that shows up however. The link is <
http://www.adobeforums.com/cgi-bin/webx?14@@.ee747eb>
2. Perform a search using <remove the crack> keywords such as you might post in a topic header.
3. Simply scan down the first page of messages <remove the crack> for a similar sounding topic (although Step 2 should've identified the same)
4. Post your question <remove the crack> if you've not found an answer.
5. Oh yeah...and <remove the crack>
6. If all else fails...remove Photoshop and reinstall. For the particular topic of this post, steps 1-6 take care of the problem for 99% of the users while a random few do appear to have other causes.
