I'm currently working on an WPF application which uses a RichTextBox. Unfortunately I'm having some difficulties.
The WPF RichTextBox (with default settings, no spellcheck) occasionally lags when I'm typing (or just holding down any key). It gives the appearance of unresponsiveness and that's undesirable.
When I couldn't find a fix, I decided to replace it with the RichTextBox from Windows Forms.
The lag is gone but the text loses its formatting (bold, italic, etc.) when using LoadFile or setting the RTF property.
Does anyone know how to remedy either problem?
I doubt that it's my system but these are the specs(this thing isn't even 6 months old!):
AMD A6-4400M APU with Radeon HD Graphics (2 CPUs), ~2.7GHz
Windows 8 64-bits (pre-installed)
