Hi,

When the NRichTextView is intiallially loaded I am getting a registry UnauthorizedAccessException. 

Then a bunch of System.IndexOutOfRangeException exceptions.  These exceptions slow down the opening of the control (first load) by about eight seconds.
See attached document for list of exceptions and glyph errors.  
Please advise ..
Thanks,
Rob

Hi Rob,

Both exceptions are handled and will not cause problems for the normal operation of the control.

1. The first exception is caused by an attempt of the control to write a timestamp in the registry - we'll remove this attempt in the next release so it will not appear anymore.

2. The second type of exception is caused by the internal OpenType glyph grid fitting program interpreter. It simply executes an invalid glyph program and generates an index out of range exception. We've deliberately left indexing unchecked for performance reasons as the .NET runtime will check the indexing anyway, but will consider adding an option to have bounds checked indexing in the interpreter to avoid exceptions.

Please let us know if you have any questions or comments.

Hi, 
Thanks for the quick response.  I have been profiling our application using ants.  I noticed that I'm losing about 8 meg of memory every time I open/close your form with your control on it and I am explicitly calling dispose()..
Nevron.Nov.Internal is growing by 2 for each control instance.  See attached instance retention graph (png file).  Is there anything else I need to do to dispose/release the control?  Our form the control is on is getting released.
Thanks,
Rob

Hi Rob,
What is the version you're currently using? There was indeed a memory leak related to the ribbon buttons icons that were holding a back reference to the control however that was fixed this year. Can you try to test with the latest release on whether the problem persists?

Here are the versions we are using.



Is this the latest?

Rob

I just download the latest and updated my references.



The leak still seems to be there.  This is REALLY a big deal for and causing issues with our release.
