Your info is too vague. We know nothing about your system, your document settings, your workspace and so on.
System is Firefox, Win 7 (SP1) running on i7 @ 2.20 GHz. Laptop - 8GB 64-bit OS
Not sure about document setting? [I am new to Photoshop... I did not do change any settings just started it up... I was just following the beginner's tutorial for creating a college, I didn't do any changes to any settings... after installation.
This morning after several hours .... the Ps "work space" showed the 2 layers - Background and photo (that I dragged and dropped)....
So it seems that performance is UNBELIEVABLELY SLOW...
I tried to resize the photo but nothing happens on the work space.... the right side bar shows photo in lower right quadrant ... but actual photo is taking most of the background (before I resized)...
Any tips on speeding up performance?
I just remembered that due to conflicts I had turned off "graphic accelerator" within videos within Firefox... would this affect anything? The resize of the photo still has not been done.
Ok... wierd!!! seems that when I put my system to sleep then restart... I see the affects of the resize!!!! HELP :-)
Moving to Photoshop forum.
