I've run in to some strange behaviour when I have two or more RadRichTextBoxes on the screen at the same time while using a custom ContextMenuContentBuilder. When I click on Paste from the context menu of any of the RadRichTextBoxes it pastes in the last one rendered. However if I paste using CTRL+V it works properly. I'm guessing I've implemented something wrong here but can't quite figure out what.
Here is the code:
By the way, I've taken all of my custom code out of the TextMenuBuilder class in an attempt to isolate the issue - I am planning to add custom menu items to each of the different RadRichTextBoxes.
