This could in fact be the mac doing font substitution. If you use a glyph that is not present in the current font then the mac will fall back to one that does have it and may fall all the way back to the system default font to display that glyph.
If it only happens in 1 out of 6 textareas, could it be something corrupt there? (I don’t know). Have you tried duplicate one of the working textareas and replace the one that doesn’t work?
Can you create a sample project that replicate the behavior?
I really would like to change this from a bug but…
The six areas go through the same code.
About a project, I cannot even figure out when it happens. It happens sometime after the last return to showing the window.
Like after activate.
I should have looked at an rtf file with a character recently added. It’s called “Hyphen Bullet” and instead of Times font, it was Lucida. The character is [quote]?[/quote]
After replacing the TextArea it would revert back to Times.
