I've used Crossover Office 4.2 with Photoline 10 now for a few months. My conclusion: is works fine!
I've tried Photoline 11: it works but has a small problem with icons. If the programs tries to "gray" icons, because they can't be used for some reason, the appear black under Crossover Office 4.2. The nightly builds (available for advocates), don't fix this, as for now.
