Even with wxPython 2.6.3.2 on windows, this behaviour seems to be the same.
The best would be to write a simply testcase for the wxPython
behaviour and report this to them. It *should* be consistant between
several platforms. However we could think about switching 
the default to alpha anyway if this is available, which would 
avoid the problem for users.

No problem, at that point I just did not have the time to inquire.

Yes, it does outside of Thuban. ;)
