I have tested 9.55 and 9.53 - there is no difference in behaviour. Here 
are some more details on the bug and on my equipment etc:

    * Computer(s): PPC PowerBook and PPC iMac (i.e. not Intel)
    * Mac OS 10.4.1

It seems to be impossible to type combining characters in Amaya. If it 
had worked, then I should have been able to use e.g. the Unicode 
Hex-input keyboard. However, that is not possible. Instead, we are using 
the PopChar X from  www.macility.com. (This of course constitutes as bug 
in itself, you could say ... But this is not unique for Amaya - 
Thundebird has the same keyboard problem. Without having the same font 
problem. )

The characters in question are (and I give the official Unicode names):

   1. COMBINING ACUTE ACCENT; As UTF-16 HEX: 0x0301; As numerical HTML
      reference: &#769;
      numerical HTML reference: &#815;

(But the behaviour should be the same in any of the combining 
diacritical of Unicode. Btw, I reccommend installing and using the free 
UnicodeChecker from earthlingsoft.net - it works similar to PopChar - 
but more advanced (and less userfriendly - perhaps).

In order to show you what happens when I insert the COMBINING ACUTE 
ACCENT, I have made 3 screenshots of the opening splash screen in Amaya 
- the word Welcome. See attachments. Here I describe what you see:

   1. image: Shows hot it looked Before typing anything.
   2. image: Status after having inserted the COMBINING ACUTE ACCENT
      above the 'o'. You now see that the insetion point moved a little
      to the right. Which is an error. In an Cocoa application, that
      doesn't happen.
   3. image: Status after having inserted the COMBINING ACUTE ACCENT
      above the 'e'. Now you can see that the insertion point moved even

With the COMBINING INVERTED BREVE BELOW, the propblem seems even worse - 
I don't even see that letter (but with the right font, I guess I would 
at least see it - right now I am not testing that issue)

Please note, if you are unfamiliar with typing _combining_ diacritica, 
that you must first type the letter and then the diacritica.

I hope this helps you identifying the problem.
