I'm not sure if this is a bug or not because I have little experience with Regular Expressions, so I'll post this as a question. First of all, I'm using a trial version of the latest build (10.1.0523) and I have a simple mask that begins with 2 literals and ends with 4 literals so my mask looks like "Q-\d{5}-ABC" and my initial input for this mask is 'Q-12345-ABC'. So when I go to change this number, I'm not allowed to change the "Q-" or the "-ABC" literals as I would expect, but after I make changes to the numeric portion and tab off the EditMaskTextBox, the "-ABC" literal is wiped out from the text box. If I tab back into the text box, it re-appears. Is my mask incorrect? Or is there something else happening here?
