How to recreate:

1. Create a new audiobook by extracting CD's
2. Start extracting
3. After extracting for a while (a few CD's) the application loses control over UI and continuing the extraction is no longer possible

Reason for this is probably a GDI handle leak. You can check this by opening Task Manager, View->Select Columns->GDI Objects. You'll see now that NokiaAudiobookManager.exe utilizes 10 000 GDI Objects, which is limit for a single process.

Op system recreated: Windows Vista SP1.
