Yesterday I found a couple bugs. Tabbing or untabbing multiple lines of text would occasionally fail. The size of the tab itself was inconsistent inside the textbox. This seems to be a glitch in the RichTextBox itself. I solved both bugs yesterday and it's working fine now. Then today I created a little promotional video for Regex Hero Professional . It's definitely of a different style than the other videos I've made. It's a little light on dialog and a little heavy on demonstration. Also I've included a couple clips from royalty-free songs I purchased from SoundSnap.com today. Let me know what you think.
