 But that's a problem of the apps. They need to get fixed. Moreover you can't 
do much anyway. You're completely out of luck in the case of identifying a 
specific window - that's simply impossible to determine somehow that some 
window is a file open dialog without the app actually saying so. Even hacking 
around the improper WM_CLASS wouldn't be easy ... what would you want to set, 
argv[0]? That still fails for Wine.
