help with gif in XRC file

Hi
I have upgrade to a recent strawberry and the installation of Wx was painless. The errors when the main frame close are gone.

I'm now learning with Wx::Demo and I'm trying to use and XRC file to build an GUI.

I have 3 files (see below). The xrc folder has been copied from ..perl\site\lib\Wx\DemoModules\files\xrc

It contains the resource.xrc file and 5 gif files that are used in resource.xrc.

When I run my code I received the following errors

13:11:10: Unknown image data format.
13:11:10: XRC error: 21: cannot create bitmap from "fileopen.gif"
...

I'm surely missing something pretty obvious, but ...

Thanks for help
