Pattern Stamp Tool

:confused: I used Photoshop 5 for years. Probably, the tool that I used the most is the Stamp.
Normally, I just selected the tool, pressing on Alt key and slided the tool across the area that I wanted to capture.
Then, without pressing any other keys, I moved across the area that I wanted the pattern to repeat itself.
Since a couple of days ago, when I do this process, the system tells me that I have to select a pattern.
:confused: :confused: I am sure that I did not change any preferences or tried to use this tool differently than before.
Why is this happening? By the way, I never had to select with any other tool an area that I wanted to capture. It was there, as soon as I move across holding down the Alt key.
Please help!

:( :eek: Well, I goofed. Yes I was using the Pattern tool not the Rubber Stamp tool. I am glad that I had no replies... I will be more careful next time.
