Hello,

 I have a problem displaying formatted(no html tags, only line ends etc.) text on one of my forms. We originally used a standart UltraTextEditor control on the form, and it worked fine, but whenever a user would click the textbox (e.g. to select the text inside), the formatting would be lost immediately. Since this was a problem, I replaced the UltraTextEditor with an UltraFormattedTextEditor and I have more problems :-(

 When the form is displayed(long after the Text property is set on the FormattedTextEditor control), the app displays a big red X over where the text should be, throws multiple exceptions:

System.Runtime.InteropServices.ExternalException: V rozhraní GDI+ došlo k obecné chybě.

and shuts down. I´ve worked around this by setting the TextRenderingMode property to GDI instead of default GDI plus. It works, but it is VERY slow - it takes it around 0.5 - 1 sec to react to scrolling or a CTRL+A keyboard shortcut. There are no events bound to the control, I´ve double checked.

I just need to display the text with the formatting intact, even after the user clicks the textbox. Plus, the CTRL+A functionality would be a nice bonus.

Here is a sample text that causes the sluggish behavior. You can imagine why I need it formatted:

Thank you for any help in advance
