[Wine] toolbar button icons appear washed out

[jprosser]

Hi Folks,
I'm trying to get MetaTrader working and am almost there except for the toolbar buttons showing up incorrectly.  They appear white with some light blue features.

I've turned on palette tracing with WINEDEBUG, and ran strace on wine to see if there was any sort of palette data being accessed, but haven't found anything.

Is there a method to discover what is causing this to happen?

Thanks,
-Joe
