missing number

[Ronald Pagel]

Hi LyX-Users,

I wrote an equation on a slide using prosper. When I view the pdf, a 
number in that equation is missing. This happens only under the 
following conditions: tiny fontsize, pdf and prosper. (See the 
comparison in the attached file.) Can someone explain that, please?

Regards,
Ronald
