wxRichTextCtrl bizarre font vertical alignment problem

[Tom Gersic]

Hi Julian,

I'm experiencing a bizarre problem with SetStyle() and parts of the text 
getting raised up just a bit for some unknown reason. See the example in 
this screenshot:

note that the word "test" is somewhat higher than the word "blah". This 
happens only when SetStyle() (or SetStyleEx()) is called on an area of 
text, but it doesn't always happen. Just in certain situations. To be 
honest, I can't seem to figure out exactly what causes it to happen and 
what doesn't, but SetStyle() is always involved. And it usually happens 
if SetStyle() is being called a second time on a bit of text that's 
already had SetStyle() called on it (i.e. a change is made to the 
style). But it doesn't always happen when calling SetStyle() more than 
once...

Any ideas what could be causing this?

Thanks,
Tom
