I am aware of this.<br>
<br>
However, this is only on i386, on 64-bit the code runs fine.<br>
I have no idea why, the code should be CPU agnostic.<br>
<br>
I have not yet had the opportunity to debug it on a i386 machine.<span class=""><font color="#888888"><br></font></span></blockquote><div><br></div><div>I just looked at it in this weekend.<br><br></div><div>After doing some tests and reading the docs i realized that is not a bug in fpjsonrtti, nor a bug at all.<br><br></div><div>First write directly 4.56 to the property (of comp type).
