crossover 3.0:
PSP7AE worked for me with - the only thing about was the child windows. you have to edit the user reg file to give them the right coordinates.
crossover 4.2
I've done an updat to cxo 4.2 and PSP 7 still workes and the child windows could now be moved on the screen. All the things i was expecting it to do are just working. even the save as does work well.
I'm using a MEPIS 2004.3 with a lot of updates from DEBIAN (testing and unstable)
