That's wierd... It works just fine here - on WinXP.
First click the button Copy Settings To Clipboard in PICMultiCalc, then set focus on the editor and press CTRL+v (or rightclick and select Paste), works like a charm.

I've tried Notepad, MCSP, Word and the online editor on this forum, here it is:
Code:
RCSTA = $90   ' Enable serial port & continuous receive
TXSTA = $24   ' Enable transmit, BRGH = 1
SPBRG = 8     ' 9600 Baud @ -0,03%
SPBRGH = 2
BAUDCON.3 = 1 ' Enable 16 bit baudrate generator
Running XP on this machine, no problems, Win7 on another, no problems.

Weird....
