Problem in scrolling item's in wxListCtrl using wxMac 2.6.3 unicode universal binary static libraries

[Amit]

Hello,

wxListCtrl's in my application has stopped responding to keyboard keys,
as a effect of this I am not able to scroll items using the keyboard.

Currently I am using
1. wxMac 2.6.3 static universal libraries with unicode flag on
2. OS : Mac OS 10.4.7,
3. IDE : Xcode 2.2.1

In the effort to resolve the above issue I tried compiling wxMac 2.6.3
libraries with Unicode flag off. surprisingly my scrolling started
working.
As my application should work with unicode characters I can't afford to
switch off the unicode flag.

Is this a known issue? If this is a known issue, Is there a patch to
fix this? Is this issue fixed in 2.8.0 build?

Thanks in advance
