Printer problems after FF finally works?

I couldn't get FF3 to work after upgrading to a new iMac. I finally figured out that it was a permissions issue and fixed that. Filter Forge will now open up in Photoshop CS5. Great. Except that immediately after this got fixed, suddenly I can't print anything from Photoshop. I can print from all other programs except PS. The only thing that has changed since the last time I printed a PS document was fixing the permissions on FF. How can this be? Has anyone else had this happen or know what might be causing this? When I click print, the dialogue box does not appear and nothing happens. It's definitely only in Photoshop and definitely only started after changing the permissions on FF but nothing else. I know it sounds crazy, but due to the timing of it, I'm thinking it very possibly is related to FF.

Thanks. Just minutes ago the print dialogue box suddenly reappeared. I won't even attempt to figure it out. Stupid things at stupid times, indeed! Hopefully that will be the last of it. My paranoia had been roused because I'd just been trying to get FF to work just as this happened, I thought it could be related. Sigh.

I love FF...upgraded from 2 to 3 and all was swell until I moved everything to a new computer...sigh. I *think* it's all working now. I do appreciate your willingness to attempt to help! Thanks.
