Error: Unable to set the Size property of the font class

[matpj]

hi all,

I have some VBA that generates pie charts or copies pastes a table of values (Depending on the selection from some comboboxes)

randomnly when it is generating one of the pies it reutrns:
run time error '1004'
Unable to set the Size property of the font class.

It is when I am running this code:

Please Login or Register  to view this content.

and highlights the .Size = 8 row.

I can run it several times without a problem, and then suddenly it will throw up this error.
can anybody suggest why it does this?
