(help) blurry text

hi you all…
i have a problem with the text inside my button. i’m using flash font.
the problem is…when i edited the text in my computer, and view it in the browser (ie & mozilla) from my computer, it looks fine and sharp enough, but when i try to view it in browser from another computer (i opened the page with another computer, not from my computer), the text is totally unfocused. i checked it with 4 other computers, and the text on the page are really blurry. only when i open it from my computer, then the page looks just fine. does anyone know why and how to solve it??
or maybe it has something to do with the fonts??maybe coz the font isn’t installed in the other computer??

for any feedbacks would be very appreciated…thanks in advance…
