QResource Stopped Working

[JPNaude]

Hi

I'm facing a problem where a QResource stopped working. It contains a set of icons which is used by a library dll. It worked but stopped working after I added a resource file to a new library's .pro file. I thought that this might have replaced the resource which I already had in the application, but even after taking it out of the new library's .pro file the old images are still not shown, and the new library without the resource still shows its icons correctly.

As I said, it did work but stopped working. All the icons in different libraries are still showing.

Any ideas on where to start debugging or what to check?
Thanks
Jaco
