Bold Script Characters in 6.0.2

I wonder how many people see this bug in Version 6.0.2? (I'm on 32-bit 
Windows Vista.)

Type (or paste in from the Special Characters Script palette):


and evaluate. Everything should be all right. Then select the output cell 
and use Menu, Format, Face, Bold to change the FontWeight to "Bold". The 
output cell will go blank and you will obtain a Messages Window with the 
error: INTERNAL SELF-TEST ERROR: NoteFont2|c|1783.

Alternatively, start a Section head and type: This section heading contains 
a Script \[ScriptCapitalF].
Again you will obtain an error message and the Script F will not display.

This happens for all Bold Script characters, but it does not happen for Bold 
Greek, Gothic or DoubleStruck.

This problem did not occur prior to Version 6.0.2.

Part of the reason for this behavior can be seen by going to 
and looking at Mathematica5.ttf (the Plain Script characters) and
Mathematica5b.ttf (supposedly the Bold Script characters).
The last file contains no characters and this seems to be the case going 
back to Version 5.2.
But Mathematica5mb.ttf does appear to have Bold and probably monospaced 

I don't know what the true source of this problem is or why there was no 
problem prior to Version 6.0.2 but it is certainly a bug.

For me, on Windows Vista, Mathematica 6.0.2 has been the most annoying, 
buggy and time consuming non-major update I have ever seen.
