Hi jm...yeah, there probably is, but I've never tried. It has to do with the text characters used for it, and you would need to find one that was pretty much blank. I used to use one that made it look like the textbox was filling up with total black (this may have it, I made it a long time ago) Thanks for the comment!
I have a quick question, how do I load your particular logons? what sort of specific program would I use for them, the only one I generally use is logon loader but I love your logon screens so much I MUST LOAD THEM!
I use Logon Studio. It's a free program and it's always worked great for me. You can get it here [link]
After you have it installed, just download a logon and click on the .logonxp file and it will install itself. If your browser changes the file to a .zip (some browsers do), just rename it from .zip to .logonxp and then click it and it will install. Let me know if you have any problems and I'll try to help you. And thanks for the great comments!
