Flickering effect using Setfont

[Andy]

Whilst working on my previous code - MoveOverControls, I added some static, checkbox, and radio buttons so I could see that the mouse over control works for those control too - which it does.

I noticed that when I use the SETFONT command inside a timer I get a flickering effect - say every 4 seconds.

I can get around this easily with a little code, but why does the text for these controls flicker?
and is there a better way to "update" the font for a control in a timer?

Just wondering.

Thanks,
Andy.
