Hi,

 I'm currently using Infragistics 8.1 and I'm having performance issue with the SpellChecker

When I put the SpellChecker to AsYouType mode

--> this.spellChecker.Mode = SpellCheckingMode.AsYouType;

And then activate the SpellChecker on a RichTextbox

--> this.spellChecker.GetSpellCheckerSettings(this.richTextBox1).Enabled = true;

 All error modes are underlined in red (as expected).

 Now when the text content gets longer (~ 100 lines of text), there is an increase delay between every key stroke and the time it gets displayed on the textbox.  So if I type a sentense, there would be a noticable delay time untill the sentense gets displayed.  And the performance issue gets worse as the richTextbox content gets larger.  Deactivating the SpellCheck would end the problem but then I don't have the mis-spelled words underline anymore.

Is there a solution you can suggest for my problem?  Thanks.

My system info:

Windows Vista SP1, 3gb RAM, Windows Form dot Net Framework 3.5,
